74AVCH1T45W6-7

Diodes Incorporated · 74 Series · SOT-26

74AVCH1T45W6-7 from Diodes Incorporated, in a SOT-26. 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 VCC(A) power_in Supply for I/O pin A and reference for DIR, operating from 1.2 V to 3.6 V.
2 GND power_in Ground reference for the device, which must be at 0 V for the 3-state and Ioff behavior to apply.
3 A bidirectional Data input/output for the A side, designed to track VCC(A), with the output in high impedance when either supply is at 0 V and inputs accepting up to 4.6 V.
4 B bidirectional Data input/output for the B side, designed to track VCC(B), with the output in high impedance when either supply is at 0 V and inputs accepting up to 4.6 V.
5 DIR input Direction control; a high level makes A the input and B the output, a low level reverses them, and its logic levels are referenced to VCC(A).
6 VCC(B) power_in Supply for I/O pin B, operating from 1.2 V to 3.6 V.
