description
TLC555 monolithic timing circuit fabricated using LinCMOSprocess. internal connection 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. TLC555C characterized operation from 70°C. TLC555I characterized operation from 40°C 85°C. TLC555M characterized operation over full military temperature range 55°C 125°C.
This device contains circuits protect inputs outputs against damage high static voltages electrostatic fields. These circuits have been qualified protect this device against electrostatic discharges (ESD) according MIL-STD-883C, Method 3015; however, advised that precautions taken avoid application voltage higher than maximum-rated voltages these high-impedance circuits. During storage handling, device leads should shorted together device should placed conductive foam. circuit, unused inputs should always connected appropriated logic voltage level, preferably either supply voltage ground. Specific guidelines handling devices this type contained publication Guidelines Handling (ESDS) Devices Assemblies available from Texas Instruments.
