TOSHIBA · Inverters · SOIC-14-175mil

TC74HC14AF from TOSHIBA, in a SOIC-14-175mil. 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 1A input Inverter 1 input with Schmitt trigger (25% VCC hysteresis; VH = 1.1 V typ. at VCC = 4.5 V). Tie unused inputs to VCC or GND.
2 1Y output Inverter 1 output (inverted 1A). Drive capability
3 2A input Inverter 2 input with Schmitt trigger (25% VCC hysteresis).
4 2Y output Inverter 2 output (inverted 2A).
5 3A input Inverter 3 input with Schmitt trigger (25% VCC hysteresis).
6 3Y output Inverter 3 output (inverted 3A).
7 GND power_in Ground / VSS reference (0 V). Common return for all six inverter stages.
8 4Y output Inverter 4 output (inverted 4A).
9 4A input Inverter 4 input with Schmitt trigger (25% VCC hysteresis).
10 5Y output Inverter 5 output (inverted 5A).
11 5A input Inverter 5 input with Schmitt trigger (25% VCC hysteresis).
12 6Y output Inverter 6 output (inverted 6A).
13 6A input Inverter 6 input with Schmitt trigger (25% VCC hysteresis).
14 VCC power_in Positive supply (2.0 to 6.0 V operating; 7.0 V absolute max). Decouple locally to GND (pin 7).

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: TOSHIBA datasheet (7 pp, sha256 4f13faf059967ad2, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
