Texas Instruments · Translators / Level Shifters · TSSOP-24

SN74LXC8T245PWR from Texas Instruments, in a TSSOP-24. 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. Operating range 1.1 V ≤ VCCA ≤ 5.5 V. Sets logic reference for A-port I/Os and control inputs (DIR, OE).
2 DIR input Direction control for all channels, referenced to VCCA. DIR=H enables A→B transmission; DIR=L enables B→A transmission. Has integrated static pull-down.
3 A1 bidirectional Channel 1 A-side I/O, referenced to VCCA. Schmitt-trigger input with integrated dynamic pull-down.
4 A2 bidirectional Channel 2 A-side I/O, referenced to VCCA.
5 A3 bidirectional Channel 3 A-side I/O, referenced to VCCA.
6 A4 bidirectional Channel 4 A-side I/O, referenced to VCCA.
7 A5 bidirectional Channel 5 A-side I/O, referenced to VCCA.
8 A6 bidirectional Channel 6 A-side I/O, referenced to VCCA.
9 A7 bidirectional Channel 7 A-side I/O, referenced to VCCA.
10 A8 bidirectional Channel 8 A-side I/O, referenced to VCCA.
11 GND power_in Device ground.
12 GND power_in Device ground.
13 GND power_in Device ground.
14 B8 bidirectional Channel 8 B-side I/O, referenced to VCCB.
15 B7 bidirectional Channel 7 B-side I/O, referenced to VCCB.
16 B6 bidirectional Channel 6 B-side I/O, referenced to VCCB.
17 B5 bidirectional Channel 5 B-side I/O, referenced to VCCB.
18 B4 bidirectional Channel 4 B-side I/O, referenced to VCCB.
19 B3 bidirectional Channel 3 B-side I/O, referenced to VCCB.
20 B2 bidirectional Channel 2 B-side I/O, referenced to VCCB.
21 B1 bidirectional Channel 1 B-side I/O, referenced to VCCB.
22 ~OE input Output Enable, active low, referenced to VCCA. Tie to GND to enable outputs; tie to VCCA to place all I/Os in high-impedance. Has integrated static pull-down.
23 VCCB power_in B-port supply voltage. Operating range 1.1 V ≤ VCCB ≤ 5.5 V. Sets logic reference for B-port I/Os.
24 VCCB power_in B-port supply voltage. Operating range 1.1 V ≤ VCCB ≤ 5.5 V. Sets logic reference for B-port I/Os.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Texas Instruments datasheet (39 pp, sha256 814fce99965a6d69, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
