Adafruit TLC551 IC Timer - CMOS 555 with 1V to 15V power, up to 1.8MHz

The TLC551 timer brings a modern twist to the classic NE555, utilizing TI’s CMOS process for enhanced performance. With compatibility across CMOS, TTL, and MOS logic, it supports frequencies up to 2 MHz, ensuring versatility in numerous electronic applications.

This component operates efficiently on a single AAA battery, accommodating a wider voltage range than its predecessors. Enhanced input impedance allows for smaller timing capacitors, resulting in precise time delays and oscillations.

Offering reliable operation, the TLC551 includes adjustable trigger and threshold levels, a reset input for cycle control, and a low impedance discharge path during low output. Its minimized supply-current spikes reduce the need for large decoupling capacitors, making it a seamless integration for both analog and digital circuit designs. The chip is conveniently available in a DIP package for easy breadboard use, covering an operational temperature range from 0°C to 70°C.
