Product Overview

The SN74AUP2G34 is a Texas Instruments low-power dual buffer gate for Signal_Chain use. Its logic function is Y = A, configured as a positive-logic dual non-inverting buffer. The recommended supply range is 0.8 to 3.6 V, with inputs specified from 0 to 3.6 V and outputs from 0 to VCC.

Electrical limits include -40 to 85 °C recommended free-air operation, 0.5 µA typical and 0.9 µA maximum supply current, and 1.5 pF typical input capacitance. At VCC = 3.3 V ±0.3 V and CL = 5 pF, propagation delay is 2.4 ns typical and 3.5 ns maximum at 25 °C.

Package options include 6-pin SC70 DCK, SON/QFN DRY, SON/uQFN DSF, and DSBGA/NanoStar WCSP YFP. The device supports 3.6 V tolerant I/O, mixed-mode signal operation, and partial-power-down use through Ioff circuitry that disables outputs to prevent damaging backflow current when powered down.
