SN74AVC1T45DCKR

Texas Instruments · 74 Series · SC-70-6

SN74AVC1T45DCKR from Texas Instruments, in a SC-70-6. 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 VCCA power_in A-port supply voltage. Sets the logic level for the A side. Operating range 1.2 V ≤ VCCA ≤ 3.6 V. Bypass locally with a ceramic capacitor.
2 GND power_in Device ground reference for both supply rails.
3 A bidirectional A-side data I/O, referenced to VCCA. Acts as input when DIR = HIGH (A→B) and as output when DIR = LOW (B→A). Typical drive ±12 mA at 3.3 V; I/Os are 4.6 V tolerant.
4 B bidirectional B-side data I/O, referenced to VCCB. Acts as output when DIR = HIGH (A→B) and as input when DIR = LOW (B→A). Typical drive ±12 mA at 3.3 V; I/Os are 4.6 V tolerant.
5 DIR input Direction control signal, referenced to VCCA. DIR = HIGH transmits A→B; DIR = LOW transmits B→A. Powered by VCCA.
6 VCCB power_in B-port supply voltage. Sets the logic level for the B side. Operating range 1.2 V ≤ VCCB ≤ 3.6 V. If either VCCA or VCCB is at GND, both ports enter high-impedance (VCC isolation).
