概述
Description
SN74LVC3G34YZPR is TI’s triple noninverting buffer with tri‑state outputs. It has three data inputs (A1, A2, A3) and three outputs (Y1, Y2, Y3) that follow the inputs when the single enable input (G) is active; when G is disabled, all outputs go high-impedance. It’s part of the LVC family, so it operates at a 1.65–3.6 V supply and is suitable for interfacing 1.8/2.5/3.3 V logic with low power and fast switching. Applications include buffering/fan-out, level shifting between compatible voltage domains, and bus interfacing. The YZPR suffix implies RoHS-compliant, tape-and-reel packaging (8-pin device).
