# TLC555IDR (Component) ## Description 555 Type, Timer/Oscillator (Single) IC 2.1MHz 8-SOIC The TLC555IDR is a low-power CMOS timer device designed as a functional replacement for the standard bipolar 555 timer while providing significantly reduced supply current and improved operating efficiency. The device supports both astable and monostable operating modes and is commonly used for timing generation, pulse shaping, oscillation, PWM generation, delay circuits, and frequency generation applications. The CMOS architecture enables low power consumption, rail-to-rail output capability, and stable timing performance over a wide operating voltage range. The device is suitable for battery-powered systems, portable electronics, industrial controls, instrumentation, consumer products, and embedded electronic designs. The TLC555IDR is supplied in a compact SOIC surface-mount package intended for automated PCB assembly and space-constrained applications. Electrical Characteristics CMOS low-power timer architecture Functional equivalent to standard 555 timer devices Wide operating supply voltage range Low quiescent supply current High input impedance Rail-to-rail output swing capability Stable threshold and trigger levels Compatible with TTL and CMOS logic levels Capable of astable and monostable operation Adjustable duty cycle and frequency operation High output drive capability for direct interfacing Low noise and improved switching performance compared to bipolar 555 timers Functional Features Precision timing generation Oscillator and clock generation Pulse-width modulation support One-shot pulse generation Delay timer implementation Missing pulse detection Frequency divider implementation Sequential timing control LED flashing and tone generation PWM motor and power control applications Package Information Surface-mount SOIC package Standard tape-and-reel packaging format Compact footprint for automated assembly RoHS compliant device construction Environmental and Operating Conditions Industrial operating temperature range ESD protection handling required Suitable for commercial and industrial embedded systems Designed for low-power electronic applications Typical Applications Timer circuits Pulse generators Oscillators PWM controllers LED flashers Alarm and tone generators Frequency generators Power management timing Embedded control systems Portable battery-powered electronics #commonpartslibrary #integratedcircuit #timer #oscillator ## Component Details - **Owner:** adrian95 - **Created:** 5/15/2026 - **Last Updated:** 5/15/2026 - **Visibility:** Public - **Datasheet URL:** https://www.ti.com/lit/ds/symlink/tlc555.pdf - **Manufacturer Part Number:** TLC555IDR - **Package or Case Code:** 8-SOIC - **Symbol Style:** parametric-v1 - **Manufacturer Name:** Texas Instruments - **Part Type:** Integrated Circuit - **Used in:** 22 projects ## Distributor Pricing (qty 1) *Pricing shown for quantity 1.
