TXB0104DR

Texas Instruments · Translators / Level Shifters · SOIC-14

TXB0104DR from Texas Instruments, in a SOIC-14. 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. 1.2V <= VCCA <= 3.6V and VCCA <= VCCB. Also supplies the OE input circuit.
2 A1 bidirectional Input/output 1 on the A port. Referenced to VCCA. Auto-sensing bidirectional level-translated I/O to B1.
3 A2 bidirectional Input/output 2 on the A port. Referenced to VCCA. Auto-sensing bidirectional level-translated I/O to B2.
4 A3 bidirectional Input/output 3 on the A port. Referenced to VCCA. Auto-sensing bidirectional level-translated I/O to B3.
5 A4 bidirectional Input/output 4 on the A port. Referenced to VCCA. Auto-sensing bidirectional level-translated I/O to B4.
6 NC unconnected No connection. Not internally connected.
7 GND power_in Ground reference for the device.
8 OE input Tri-state output-mode enable, referenced to VCCA. Pull OE low to place all outputs in high-impedance (tri-state) mode; a pulldown resistor to GND is recommended to ensure Hi-Z during power up/down.
9 NC unconnected No connection. Not internally connected.
10 B4 bidirectional Input/output 4 on the B port. Referenced to VCCB. Auto-sensing bidirectional level-translated I/O to A4.
11 B3 bidirectional Input/output 3 on the B port. Referenced to VCCB. Auto-sensing bidirectional level-translated I/O to A3.
12 B2 bidirectional Input/output 2 on the B port. Referenced to VCCB. Auto-sensing bidirectional level-translated I/O to A2.
13 B1 bidirectional Input/output 1 on the B port. Referenced to VCCB. Auto-sensing bidirectional level-translated I/O to A1.
14 VCCB power_in B-port supply voltage. 1.65V <= VCCB <= 5.5V. Must be greater than or equal to VCCA.
