onsemi · Inverters · TSSOP-14

MM74HC14MTCX from onsemi, in a TSSOP-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 A1 input Schmitt-trigger input to inverter 1. VT+ typ 2.7 V, VT- typ 1.8 V at VCC = 4.5 V; hysteresis typ 0.9 V. Max input current ±1 µA.
2 Y1 output Inverted Schmitt-trigger output of gate 1 (Y1 = !A1). Drives ±4 mA at VCC = 4.5 V (VOH ≥ 3.98 V, VOL ≤ 0.26 V).
3 A2 input Schmitt-trigger input to inverter 2. Same thresholds and hysteresis as A1.
4 Y2 output Inverted Schmitt-trigger output of gate 2 (Y2 = !A2).
5 A3 input Schmitt-trigger input to inverter 3.
6 Y3 output Inverted Schmitt-trigger output of gate 3 (Y3 = !A3).
7 GND power_in Ground reference (0 V). Common return for VCC.
8 Y4 output Inverted Schmitt-trigger output of gate 4 (Y4 = !A4).
9 A4 input Schmitt-trigger input to inverter 4.
10 Y5 output Inverted Schmitt-trigger output of gate 5 (Y5 = !A5).
11 A5 input Schmitt-trigger input to inverter 5.
12 Y6 output Inverted Schmitt-trigger output of gate 6 (Y6 = !A6).
13 A6 input Schmitt-trigger input to inverter 6.
14 VCC power_in Positive supply. Recommended 2 V to 6 V; absolute max 7.0 V. Quiescent supply current typ 2 µA (max 20 µA at 25 °C).
