Texas Instruments · Logic ICs · SC-70-5

SN74CBTD1G125DCKR 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 Active-high output-enable control that disables the switch when high, with TTL-compatible levels (VIH min 2 V, VIL max 0.8 V).
2 A bidirectional Switch terminal A, connected to terminal B when OE is low with a typical 5 Ω on-state connection.
3 GND power_in Ground reference for the device.
4 B bidirectional Switch terminal B, connected to terminal A when OE is low with a typical 5 Ω on-state connection.
5 VCC power_in Supply voltage, recommended 4.5 V to 5.5 V, with an absolute maximum of 7 V; unused control inputs must be held at VCC or GND.
