概述

Description

SN74AVC2T245GUX is a dual 4‑bit bidirectional bus transceiver with 3‑state outputs from TI’s AV C family. It provides bidirectional data transfer between two voltage domains via A[3:0] on VCCA and B[3:0] on VCCB. A common DIR input selects the data direction (A→B or B→A); an OE input tri-states both sides. It supports independent supply rails for the two sides, enabling level shifting between voltages. The GUX suffix denotes the RoHS‑compliant package/tape‑and‑reel variant. Typical uses include interfacing a microcontroller to peripherals or memory with different I/O voltages, bus bridging, and general bidirectional data transfer. Key benefits: high‑speed CMOS, low power, simple control (one direction pin and one OE), and no extra gate required for level shifting. For exact pinout and electrical specs, consult the datasheet (VCCA/VCCB ranges, propagation delays, current limits).

Features

Here are the main features of 74AVC2T245GUX:
- Two-bit bidirectional bus transceiver with 3-state outputs.
- Separate supply rails on each side (A-side and B-side) for voltage-level translation between two domains.
- DIR input to select data flow direction (A→B or B→A).
- OE input to enable/disable (tri-state) both sides.
- CMOS/TTL-compatible inputs; supports standard AVC I/O ranges.
- Designed for low power with fast CMOS performance.
- ESD protection and robust I/O protection suitable for mixed-voltage systems.
- Available in Nexperia’s GUX package (lead-free, standard packaging).

Package

The 74AVC2T245GUX is supplied in an 8-pin UQFN/USON (WSON) package (3.0 mm × 3.0 mm, exposed pad QFN, 0.5 mm pitch).

Pinout

Pin count: 8 pins.
Function: A dual-supply, 2-bit non‑inverting bidirectional bus transceiver and voltage‑level translator. It provides two A↔B channels (A1/A2 ⇄ B1/B2) for asynchronous logic-level translation between separate VCCA and VCCB rails, with a direction control (DIR) and an output‑enable (OE, typically active‑low) to control data flow and bus isolation.

Manufacturer

Manufacturer: Texas Instruments (part number SN74AVC2T245GUX).
What kind of company: Texas Instruments is a large, multinational semiconductor company that designs and manufactures analog, embedded processing, mixed‑signal and logic integrated circuits (ICs) used across consumer, industrial, and automotive markets.

Application

Applications of 74AVC2T245GUX:
- Bidirectional level shifting and buffering between two voltage domains (VCCA vs VCCB)
- Interfaces for microcontrollers, FPGAs/CPLDs, and memories on mixed-supply buses
- Backplane/board-to-board signaling and I/O expansion with tri-state outputs
- Signal isolation and protection in consumer, industrial, and automotive electronics
- Glue logic for high-speed digital data paths in mixed-voltage systems
(3-state, direction-controlled bus transceiver for flexible interconnects.)

Equivalent

Direct equivalents: SN74AVC2T245 (TI) and the same 74AVC2T245 offered by Nexperia, ON Semiconductor, Diodes, etc. Functional alternatives (verify pinout/voltage specs before substituting): TXB0102 or TXS0102 (auto-directional 2‑bit translators), and 74LVC2T45 / SN74LVC2T45 (2‑bit dual‑supply level translators with direction control).
