概述

Description

The SN74AVC4T234ZSUR is TI’s 4‑bit bidirectional bus transceiver/voltage translator. It connects two voltage domains (A-side and B-side) and translates signals between them, suitable for bridging different logic levels (for example, 3.3V to 5V). It provides four independent I/O channels, tri‑state outputs, and an output-enable (OE) control to place the buses in high impedance when needed. The device uses a low-power, fast “4T” translation architecture and is intended for mixed‑voltage I/O expansion and interfacing microcontrollers/peripherals operating on different logic supplies. The suffix ZSUR is TI’s packaging code for a RoHS-compliant package variant (tape-and-reel).

Features

Here are the key features of SN74AVC4T234ZSUR:
- 4-bit bidirectional voltage-level translator/buffer with dual supply rails (VCCA and VCCB)
- Works across 1.65 V to 3.6 V on both sides (dual-supply operation)
- Bidirectional translation between the two voltage domains
- 3-state outputs with an enable control (OE)
- Ioff specification for partial-power-down support (no back-powering)
- Auto-direction/bidirectional capability (no external direction pin required on basic use)
- Low power consumption in static operation
- ESD protection on I/O pins
- Temperature range: -40°C to 125°C (industrial)
- Package: ZSUR (14-pin) with lead-free, halogen-free compliance
Common applications: level shifting between microcontrollers/peripherals operating at different I/O voltages, data bus buffering, and interface bridging in mixed-supply systems.

Package

The SN74AVC4T234ZSUR uses a 16‑pin small‑outline package (TSSOP‑16 / SOIC‑16), Pb‑free RoHS compliant.

Pinout

- Pin count: 20 pins (TSSOP/SOIC-20 package, indicated by ZSUR suffix).
- Function: 4-bit bidirectional voltage-level translator/buffer with dual supplies. It translates between A-side (A1–A4) and B-side (B1–B4) I/O ports, using two supply rails (VCCA and VCCB). Direction is controlled by DIR (data flows A→B or B→A for all four bits), with OE to enable/disable outputs. GND common.

Manufacturer

Manufacturer: Texas Instruments Incorporated (TI).
What kind of company: TI is an American multinational semiconductor company that designs and manufactures analog and digital integrated circuits, microcontrollers, sensors, and related semiconductor products for a wide range of industries.

Application

SN74AVC4T234ZSUR is a 4‑bit, bidirectional voltage‑level translator/buffer with dual supplies and 3‑state outputs. Typical applications:
- Level shifting between voltage domains (e.g., 1.8–3.3/5 V)
- Bidirectional data/address bus buffering
- Interfacing MCUs/SoCs to peripherals, memory, sensors
- Portable and automotive/industrial IO translation
- Bus isolation and signal integrity improvement in mixed‑voltage systems
