DESCRIPTION/ORDERING INFORMATION
TLC555 monolithic timing circuit fabricated using LinCMOSprocess. timer fully compatible with CMOS, TTL, logic operates frequencies MHz. Because high input impedance, this device uses smaller timing capacitors than those used NE555. result, more accurate time delays oscillations possible. Power consumption across full range power supply voltage. Like NE555, TLC555 trigger level equal approximately one-third supply voltage threshold level equal approximately two-thirds supply voltage. These levels altered control voltage terminal (CONT). When trigger input (TRIG) falls below trigger level, flip-flop output goes high. TRIG above trigger level threshold input (THRES) above threshold level, flip-flop reset output low. reset input (RESET) override other inputs used initiate timing cycle. RESET low, flip-flop reset output low. Whenever output low, low-impedance path provided between discharge terminal (DISCH) GND. unused inputs should tied appropriate logic level prevent false triggering. While CMOS output capable sinking over sourcing over TLC555 exhibits greatly reduced supply-current spikes during output transitions. This minimizes need large decoupling capacitors required NE555. TLC555 characterized operation over full automotive temperature range -40°C 125°C. ORDERING INFORMATION
