概述

Description

The SN74LVC3G34YZPR is a Texas Instruments low‑voltage CMOS buffer/driver in the LVC3G34 family. It provides three independent buffers with tri‑state (3‑state) outputs, designed to drive and buffer signals between 1.65 V and 3.6 V logic domains.
Key points
- Three buffer channels with tri‑state outputs (outputs can be disabled via an enable/runtime control)
- Supply voltage: Vcc = 1.65–3.6 V (LVC family)
- Fast, low‑power CMOS operation; suitable for high‑speed logic interfacing
- Small RoHS‑compliant package (YZPR denotes the specific 8‑pin package style)
Common uses
- Buffering and driving signals in mixed‑voltage designs
- Level shifting between voltage domains
- Increasing fan-out to reduce loading on a microcontroller/FPGA I/O
Notes
- Check the datasheet for exact pinout, enable pin behavior, timing specs, and temperature range (often -40 to 125°C for industrial variant).

Features

- Three independent noninverting buffers
- 3-state outputs with a common enable (OE)
- Wide supply: 1.65 V to 3.6 V (LVC family)
- Ioff for partial-power-down support (no back-powering)
- Low static/dynamic power; high-speed operation
- ESD protection (HBM) on inputs/outputs
- Temperature range: -40°C to 125°C
- 8-pin package (YZPR variant)

Package

It’s in an 8‑pin VSSOP package (VSSOP-8).

Pinout

- Pin count: 9 pins (SC70/TSOT-23 type package commonly)
- Function: SN74LVC3G34 is a triple 3-state buffer/driver with a common output enable. It provides three noninverting buffers (inputs A1, A2, A3 → outputs Y1, Y2, Y3) with a shared OE. When OE is high, outputs follow inputs; when OE is low, all outputs are in high-impedance. Supply voltage typically 1.65–3.6 V.

Manufacturer

- Manufacturer: Texas Instruments (TI)
- What kind of company: An American multinational corporation that designs and manufactures semiconductors and integrated circuits, specializing in analog, mixed-signal, and digital ICs. It is one of the world's largest semiconductor companies.

Application

SN74LVC3G34YZPR is a 3-channel, non-inverting buffer/line driver with tri-state outputs. Common applications:
- Buffering and driving data/address lines between ICs or MCUs
- Level shifting between voltage domains
- I/O expansion for microcontrollers/FPGA
- Bus isolation with enable/disable control on shared buses
- Improving signal integrity and fanout in high-speed designs
- Supporting external memory interfaces and peripheral signaling in embedded systems
