TLC556IDR

Texas Instruments · Timers / Counters · SOIC-14

TLC556IDR from Texas Instruments, in a SOIC-14. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 DISCH output Open collector output to discharge timing capacitor.
2 THRES input End of timing input; THRES > CONT sets output low and discharge low.
3 CONT input Controls comparator thresholds; outputs 2/3 VDD and allows bypass capacitor connection.
4 RESET input Active low reset input forces output and discharge low.
5 OUT output High current timer output signal.
6 TRIG input Start of timing input; TRIG < 1/2 CONT sets output high and discharge open.
7 GND power_in Ground.
8 TRIG input Start of timing input; TRIG < 1/2 CONT sets output high and discharge open.
9 OUT output High current timer output signal.
10 RESET input Active low reset input forces output and discharge low.
11 CONT input Controls comparator thresholds; outputs 2/3 VDD and allows bypass capacitor connection.
12 THRES input End of timing input; THRES > CONT sets output low and discharge low.
13 DISCH output Open collector output to discharge timing capacitor.
14 VDD power_in Power-supply voltage; 2V to 15V.
