Texas Instruments TLC555CP Low Power 555 Timer, DIP8, 2.1MHz

The Texas Instruments TLC555CP is a precision timing circuit fabricated using advanced LinCMOS™ technology. This monolithic timer offers full compatibility with CMOS, TTL, and MOS logic systems, making it a versatile choice for a wide range of digital and analogue applications. Its high input impedance allows for the use of significantly smaller timing capacitors compared to traditional NE555 timers, enabling more accurate and stable time delays and oscillations.

A standout feature is its exceptionally low power consumption across the full spectrum of its power supply voltage, from 2V to 15V. The CMOS output is capable of swinging rail-to-rail and provides a high output current capability, ensuring robust performance. The low supply current minimises spikes during output transitions, contributing to cleaner signal integrity. Furthermore, the device includes substantial ESD protection, exceeding 2000V per MIL-STD-883C, Method 3015.2, enhancing its durability in sensitive environments.
