# TXU0102DCUR

**Texas Instruments** · Translators, Level Shifters · VSSOP-8

TXU0102DCUR from Texas Instruments, in a VSSOP-8. 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 | B2Y | output | Channel 2 push-pull output on the B side, referenced to VCCB. Drives the translated logic level of input A2 onto the B port. |
| 2 | GND | power_in | Device ground reference for both A- and B-side supplies. |
| 3 | VCCA | power_in | A-port supply voltage. Operating range 1.1 V ≤ VCCA ≤ 5.5 V. Sets the logic level reference for the A-side inputs (A1, A2). |
| 4 | A2 | input | Channel 2 Schmitt-trigger input on the A side, referenced to VCCA. Signal is translated to VCCB level and driven out on B2Y. |
| 5 | A1 | input | Channel 1 Schmitt-trigger input on the A side, referenced to VCCA. Signal is translated to VCCB level and driven out on B1Y. |
| 6 | OE | input | Output Enable. Pull to GND to place all outputs in high-impedance mode; pull to VCCA or VCCB to enable all outputs. May be referenced to either supply rail. |
| 7 | VCCB | power_in | B-port supply voltage. Operating range 1.1 V ≤ VCCB ≤ 5.5 V. Sets the logic level reference for the B-side outputs (B1Y, B2Y). |
| 8 | B1Y | output | Channel 1 push-pull output on the B side, referenced to VCCB. Drives the translated logic level of input A1 onto the B port. |
