Texas Instruments · Buffer/Driver/Transceiver · VSSOP-8

SN74LVC3G34DCUR 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 1A input Buffer 1 input. Accepts voltages up to 5.5 V regardless of VCC (can be used as a down translator).
7 1Y output Buffer 1 output. Non-inverting output of 1A (Y = A). Drives ±24 mA at VCC = 3.3 V.
3 2A input Buffer 2 input. Accepts voltages up to 5.5 V regardless of VCC.
5 2Y output Buffer 2 output. Non-inverting output of 2A. Drives ±24 mA at VCC = 3.3 V.
6 3A input Buffer 3 input. Accepts voltages up to 5.5 V regardless of VCC.
2 3Y output Buffer 3 output. Non-inverting output of 3A. Drives ±24 mA at VCC = 3.3 V.
4 GND power_in Ground reference for the device.
8 VCC power_in Supply voltage. Operating range 1.65 V to 5.5 V (data retention only down to 1.5 V). Bypass with a decoupling capacitor to GND.

Provenance

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

  • Datasheet: Texas Instruments datasheet (23 pp, sha256 eea85b84a07fc5a5, 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).
