I reviewed the part project against the TI 555-family datasheet and the current project metadata.
Datasheet URL
A datasheet URL is already set, and it points to an official TI document link, so I did not change it. The sync workflow says to keep the existing Datasheet URL when it already exists and is official/canonical
Part info review
Current project properties show:
  • MPN: NE555P
  • Manufacturer: Texas Instruments
  • Part Type: Integrated Circuit
  • Current package description: DIP-8 / PDIP in the description and assets
  • Datasheet URL: official TI link already present
From the TI datasheet I could confirm:
  • Device family / functional description: Precision Timing Circuit / Precision Timer
  • Packages in datasheet family: PDIP, SOIC, TSSOP, WQFN
  • PDIP pin count: 8
  • Supply voltage: 4.5 V to 18 V
  • Operating free-air temperature: −55°C to 125°C
  • Output capability: up to 200 mA source/sink, with ±225 mA absolute max output current
  • Typical use: timing from microseconds to hours, with astable frequency set by two resistors and one capacitor
These values came directly from the TI datasheet URL in the project via targeted extraction, following the datasheet-query guidance to query exact sections instead of broad summaries
Symbol cross-check
The datasheet pinout for PDIP-8 is:
  1. GND
  2. TRIG
  3. OUT
  4. RESET
  5. CONT
  6. THRES
  7. DISCH
  8. VCC
Your schematic symbol terminals are:
  • GND → Pin 1
  • TRIG → Pin 2
  • OUT → Pin 3
  • RESET → Pin 4
  • CONT → Pin 5
  • THRES → Pin 6
  • DISCH → Pin 7
  • VCC → Pin 8
Result
  • Pin count matches: 8/8
  • Pin names match
  • Pin numbers match
  • No missing or extra terminals found
That matches the requirement that terminal count and pin numbering exactly follow the datasheet
Pin description / pin type audit
From the datasheet, the pin functions are:
  • GND — Ground
  • TRIG — Input, start of timing input
  • OUT — Output, high-current timer output
  • RESET — Input, active-low reset
  • CONT — Input/output, comparator-threshold control / bypass node
  • THRES — Input, end-of-timing input
  • DISCH — Output, open-collector discharge output
  • VCC — Input, supply voltage
Mismatches found
All 8 terminals currently have Pin Type = Unspecified in the project schematic output.
That is the main mismatch. Based on the datasheet, they should be approximately:
  • GND → Ground
  • TRIG → Input
  • OUT → Output
  • RESET → Input
  • CONT → Unspecified or possibly Input/Output contextually, since the datasheet describes it as input/output
  • THRES → Input
  • DISCH → Output
  • VCC → Power In
Also, I do not see per-pin short descriptions populated in the current terminal properties, so the symbol metadata is incomplete versus the datasheet-driven best practice
Footprint cross-check
What I could verify:
  • The project includes a footprint asset named DIP-8_W7.62mm
  • The layout contains 8 pads
  • Pad designators map to the same logical pin names as the symbol terminals:
    • GND, TRIG, OUT, RESET, CONT, THRES, DISCH, VCC
Result
  • Package style is consistent with a through-hole 8-pin DIP/PDIP part
  • Pad count matches the datasheet pin count
  • Logical pad naming matches the symbol pin naming
Limitation
I could not fully validate the exact land-pattern geometry from the current tool outputs alone. The asset naming strongly suggests the expected 300 mil / 7.62 mm row spacing DIP-8 footprint, and nothing in the project data conflicts with that, but I can only call this a likely match, not a full dimensional verification from the extracted package drawing.
Description / metadata observations
Your current description says:
  • “555 Type, Timer/Oscillator (Single) IC 100kHz 8-PDIP”
  • “NE555 DIP-8 through hole”
That is broadly consistent with the datasheet and part identity.
One small metadata note:
  • The TI datasheet extraction returned the family title as SE555 rather than the exact orderable NE555P, because TI uses a family datasheet covering multiple 555 variants.
  • Your project MPN = NE555P is still reasonable and appears more specific than the family title.
Key specs summary
  • Part: NE555P
  • Manufacturer: Texas Instruments
  • Function: Precision timer / oscillator
  • Package: PDIP-8, through-hole
  • Pin count: 8
  • Supply range: 4.5 V to 18 V
  • Operating temperature: −55°C to 125°C
  • Output drive capability: source/sink up to 200 mA
  • Absolute max output current: ±225 mA
Final verdict Correct
  • Datasheet URL already set and official
  • MPN/manufacturer generally consistent
  • Symbol pin count, names, and numbering all match the datasheet
  • Footprint style and pad count are consistent with PDIP-8
  • Pad names align with symbol terminal names
Issues to flag
  • All terminal Pin Type fields are still Unspecified
  • Pin descriptions appear missing
  • Exact footprint geometry was not fully dimension-verified from available tool output
If you want, I can next update the terminal metadata so each pin gets the correct Pin Type and concise Pin Description from the datasheet.

NE555P

NE555P thumbnail
555 Type, Timer/Oscillator (Single) IC 100kHz 8-PDIP NE555 DIP-8 through hole The NE555P is a classic and widely used precision timer IC manufactured by companies like Texas Instruments and others. It belongs to the popular 555 timer family and is designed for generating accurate time delays, oscillations, and pulse signals.
The “P” variant refers to the PDIP (Plastic Dual In-line Package), making it ideal for through-hole mounting, breadboarding, and prototyping.
Internally, the NE555P consists of:
Two comparators A flip-flop A discharge transistor A voltage divider network
These blocks allow flexible configuration for timing and waveform generation. Key Features Timing & Operation Modes Monostable mode (one-shot pulse generation) Astable mode (continuous oscillator) Bistable mode (flip-flop operation) Electrical Characteristics Supply voltage range: 4.5V to 16V Output can source or sink up to 200 mA Adjustable duty cycle Performance High timing accuracy and stability Timing range from microseconds to hours (depends on external R and C) Temperature-stable operation Package & Usability 8-pin DIP (through-hole) package Easy to use for: Breadboards DIY electronics Educational projects Common Applications LED flashers and blinkers Pulse generation Time delay circuits PWM control (e.g., dimming LEDs, motor speed control) Tone/sound generation #Timer #commonpartslibrary
