TLC555CP

Texas Instruments · Timers / Counters · PDIP-8

TLC555CP from Texas Instruments, in a PDIP-8. 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 GND power_in Ground terminal.
2 TRIG input Trigger timing input; output goes high and discharge pin enters open-circuit state when trigger voltage falls below 1/2 of control voltage.
3 OUT output High-current timing output signal with CMOS rail-to-rail swing capability.
4 RESET input Active-low reset input that forces output and discharge pin to low level.
5 CONT input Control voltage input that sets comparator threshold levels; provides internal 2/3 VDD reference when left open and accepts bypass capacitor connection.
6 THRES input Threshold timing input; output and discharge pin go low when threshold voltage exceeds control voltage.
7 DISCH tri_state Open-collector discharge output capable of rapidly discharging external timing capacitor.
8 VDD power_in Positive supply voltage; operating range 2V to 15V depending on device grade.

CAD (KiCad official)

  • Symbol: TLC555CP
  • Footprint: Package_DIP:DIP-8_W7.62mm
  • 3D model: PDIP-8 (KiCad packages3D, STEP)
  • 3D model files: tlc555cp-etched.step / tlc555cp-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tlc555cp.step / tlc555cp.glb are the bare package body.
