# TLC555IP (Component) ## Description 555 Type, Timer/Oscillator (Single) IC 2.1MHz 8-PDIP The TLC555 is a CMOS monolithic timing circuit. The timer is fully compatible with CMOS, TTL, and MOS logic and operates at frequencies up to 2MHz. Because of a high input impedance, this device supports smaller timing capacitors than those supported by the NE555 or LM555. As a result, more accurate time delays and oscillations are possible. Power consumption is low across the full range of power-supply voltage. • Very low power consumption: – 1mW typical at VDD = 5V • Capable of operation in astable mode • CMOS output capable of swinging rail to rail • High output current capability – Sink: 100mA typical – Source: 10mA typical • Output fully compatible with CMOS, TTL, and MOS • Low supply current reduces spikes during output transitions • Single-supply operation from 2V to 15V • Functionally interchangeable with the NE555; has same pinout • ESD protection exceeds 1000V per ANSI/ESDA/ JEDEC JS-001 • Available in Q-temp automotive – High-reliability automotive applications – Configuration control and print support – Qualification to automotive standards #CommonPartsLibrary #IntegratedCircuit ## Component Details - **Owner:** lcsc - **Created:** 11/5/2024 - **Last Updated:** 6/1/2026 - **Visibility:** Public - **Symbol Style:** parametric-v1 - **LCSC Part Number:** C1520182 - **Package or Case Code:** DIP-8_L10.1-W6.3-P2.54-LS7.6-BL - **Manufacturer Part Number:** TLC555IP - **Manufacturer Name:** TI(德州仪器) - **Part Type:** Timer - **License:** https://creativecommons.org/licenses/by/4.0/ - **JLCPCB Part Class:** Extended Part - **Datasheet URL:** https://www.ti.com/lit/ds/symlink/tlc555.pdf?HQS=dis-dk-null-digikeymode-dsf-pf-null-wwe&ts=1775078142355&ref_url=https%253A%252F%252Fwww.ti.com%252Fgeneral%252Fdocs%252Fsuppproductinfo.tsp%253FdistId%253D10%2526gotoUrl%253Dhttps%253A%252F%252Fwww.ti.com%252Flit%252Fgpn%252Ftlc555 - **Used in:** 72 projects ## Distributor Pricing (qty 1) *Pricing shown for quantity 1.
