Overview
The TLC555CPS, produced by Texas Instruments, is a monolithic timing circuit fabricated using the TI LinCMOS™ technology. This timer is fully compatible with CMOS, TTL, and MOS logic and operates at frequencies up to 2 MHz. It is designed for general-purpose timing applications and offers low power consumption across a wide range of power-supply voltages, from 2 V to 15 V. The TLC555CPS is functionally interchangeable with the NE555 and has the same pinout, making it a versatile component for various timing and pulse generation needs.
