TLC556CDR

Texas Instruments · Timers / Counters · SOIC-14

TLC556CDR from Texas Instruments, in a SOIC-14. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 DISCH output Open-collector output for discharging the timing capacitor.
2 THRES input Threshold input; when THRES exceeds CONT, output and discharge pins are set low.
3 CONT input Control voltage input that sets comparator thresholds and provides 2/3 VDD reference when open-circuited.
4 RESET input Active-low reset input that forces output and discharge pins low.
5 OUT output High-current timer output signal.
6 TRIG input Trigger input; when TRIG is below 1/2 CONT, output goes high and discharge pin opens.
7 GND power_in Ground connection.
8 TRIG input Trigger input; when TRIG is below 1/2 CONT, output goes high and discharge pin opens.
9 OUT output High-current timer output signal.
10 RESET input Active-low reset input that forces output and discharge pins low.
11 CONT input Control voltage input that sets comparator thresholds and provides 2/3 VDD reference when open-circuited.
12 THRES input Threshold input; when THRES exceeds CONT, output and discharge pins are set low.
13 DISCH output Open-collector output for discharging the timing capacitor.
14 VDD power_in Power supply voltage.
