TLC3555-Q1 High-Speed CMOS Timer

Texas Instruments TLC3555-Q1 High-Speed CMOS Timer is a monolithic timing circuit fabricated using a TI CMOS process. The timer is fully compatible with CMOS, TTL, and MOS logic and operates at frequencies to 3MHz and even beyond. The TLC3555-Q1 improves upon the existing TLC555-Q1 from both a performance and feature standpoint, with tighter specification tolerances and additional features, such as thermal shutdown and power-on reset. The trigger, threshold, and reset logic of the TLC3555-Q1 follow the same truth table as the TLC555-Q1. Set the reset pin (RESET) high for typical operation, or set the reset pin low to reset the flip-flop and force the output low. The TLC3555-Q1 features an internal pull-up resistor from RESET to VDD, which can reduce passive count and save board area.
