SN74AVCH1T45DCKT

Texas Instruments · Translators, Level Shifters · SC-70-6

SN74AVCH1T45DCKT from Texas Instruments, in a SC-70-6. 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 VCCA power_in A port power supply voltage, 1.2V ≤ VCCA ≤ 3.6V
2 GND power_in Ground connection
3 A bidirectional Input/output A referenced to VCCA, supports 1.2V to 3.6V I/O voltage with bus-hold circuitry
4 B bidirectional Input/output B referenced to VCCB, supports 1.2V to 3.6V I/O voltage with bus-hold circuitry
5 DIR input Direction control input referenced to VCCA; high level enables A to B data transmission, low level enables B to A data transmission
6 VCCB power_in B port power supply voltage, 1.2V ≤ VCCB ≤ 3.6V
