Texas Instruments · Inverters · SC-70-5

SN74AUP1T14DCKR from Texas Instruments, in a SC-70-5. 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 NC unconnected No internal connection. Leave floating or tie to VCC/GND for best signal integrity.
2 A input Schmitt-trigger logic input (lower-level input). Accepts 1.8 V, 2.5 V, or 3.3 V LVCMOS signals. VT+ typ 1.1 V @ VCC=2.5 V (1.19 V @ VCC=3.3 V); VT- typ 0.35 V @ VCC=2.5 V (0.5 V @ VCC=3.3 V); hysteresis ≈ 210 mV.
3 GND power_in Ground reference (0 V) for the device.
4 Y output CMOS output referenced to VCC. Y = /A (inverter). Drive capability 4 mA at VCC=3.3 V (3.1 mA at VCC=2.5 V); VOH typ 2.55 V and VOL typ 0.45 V at VCC=3.3 V.
5 VCC power_in Supply voltage input; recommended operating range 2.3 V to 3.6 V (absolute max 4.6 V). Sets output CMOS level. Bypass locally with a 0.1 µF capacitor.
