CAHCT1G125QDCKRG4Q

Texas Instruments · Buffers, Drivers, Receivers, Transceivers · SC-70-5

CAHCT1G125QDCKRG4Q from Texas Instruments, in a SC-70-5. 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 OE input Output Enable control input; high disables Y to high-impedance state, low enables Y output from A input
2 A input Data input A; TTL-compatible input with VIH min 2V and VIL max 0.8V at VCC 4.5-5.5V
3 GND power_in Ground; circuit reference voltage
4 Y tri_state Output Y; tri-state output with ±8mA drive capability at 5V, high-impedance when OE is high
5 VCC power_in Power supply; 3V to 5.5V recommended operating range
