Texas Instruments · Translators / Level Shifters · SOIC-16

SN74AVC4T245DR from Texas Instruments, in a SOIC-16. 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 power supply voltage. 1.2 V <= VCCA <= 3.6 V. Sets the reference voltage for the A-port I/Os and the DIR/OE control inputs.
2 1DIR input Direction-control input for the '1' 2-bit port pair (1A1/1A2 <-> 1B1/1B2). HIGH transmits A->B, LOW transmits B->A. Referenced to VCCA.
3 2DIR input Direction-control input for the '2' 2-bit port pair (2A1/2A2 <-> 2B1/2B2). HIGH transmits A->B, LOW transmits B->A. Referenced to VCCA.
4 1A1 bidirectional Input/output 1A1 on the A side of the '1' transceiver bit. Referenced to VCCA (1.2 V to 3.6 V).
5 1A2 bidirectional Input/output 1A2 on the A side of the '1' transceiver bit. Referenced to VCCA (1.2 V to 3.6 V).
6 2A1 bidirectional Input/output 2A1 on the A side of the '2' transceiver bit. Referenced to VCCA (1.2 V to 3.6 V).
7 2A2 bidirectional Input/output 2A2 on the A side of the '2' transceiver bit. Referenced to VCCA (1.2 V to 3.6 V).
8 GND power_in Ground reference for the device. Must be tied to system ground.
9 GND power_in Ground reference for the device. Must be tied to system ground.
10 2B2 bidirectional Input/output 2B2 on the B side of the '2' transceiver bit. Referenced to VCCB (1.2 V to 3.6 V).
11 2B1 bidirectional Input/output 2B1 on the B side of the '2' transceiver bit. Referenced to VCCB (1.2 V to 3.6 V).
12 1B2 bidirectional Input/output 1B2 on the B side of the '1' transceiver bit. Referenced to VCCB (1.2 V to 3.6 V).
13 1B1 bidirectional Input/output 1B1 on the B side of the '1' transceiver bit. Referenced to VCCB (1.2 V to 3.6 V).
14 2OE input Active-low 3-state output enable for the '2' transceiver bit. Drive LOW to enable outputs, HIGH to place 2A1/2A2/2B1/2B2 in Hi-Z. Referenced to VCCA.
15 1OE input Active-low 3-state output enable for the '1' transceiver bit. Drive LOW to enable outputs, HIGH to place 1A1/1A2/1B1/1B2 in Hi-Z. Referenced to VCCA.
16 VCCB power_in B-port power supply voltage. 1.2 V <= VCCB <= 3.6 V. Sets the reference voltage for the B-port I/Os.
