NE555PWR

Texas Instruments · Timers / Counters · TSSOP-8

NE555PWR from Texas Instruments, in a TSSOP-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.
2 TRIG input Start of timing input; TRIG < ½ CONT sets output high and discharge open.
3 OUT output High current timer output signal.
4 RESET input Active low reset input forces output and discharge low.
5 CONT bidirectional Controls comparator thresholds; outputs 2/3 × VCC; allows bypass capacitor connection.
6 THRES input End of timing input; THRES > CONT sets output low and discharge low.
7 DISCH output Open collector output to discharge timing capacitor.
8 VCC power_in Input supply voltage, 4.5 V to 16 V.

CAD (KiCad official)

  • Symbol: NE555PWR
  • Footprint: Package_SO:TSSOP-8_3x3mm_P0.65mm
  • 3D model: TSSOP-8 (KiCad packages3D, STEP)
  • 3D model files: ne555pwr-etched.step / ne555pwr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ne555pwr.step / ne555pwr.glb are the bare package body.
