概要

Description

74AVC4T3144GU12X is a four-channel bidirectional level-translating buffer from TI’s 74AVC4T family. It provides four A↔B signal paths that translate between two supply domains (VCCA and VCCB) to connect devices running different logic voltages.
Key points
- 4 independent channels (A1–A4 to B1–B4) with automatic direction when driving signals.
- Dual-supply design: VCCA on one side, VCCB on the other; enables level shifting between voltage domains.
- Tri-state outputs with a common output-enable (OE) control for high-impedance when not in use.
- Suitable for interfacing microcontrollers, memories, sensors, or other ICs across different voltage levels, with fast propagation and low power.
- GU12X suffix denotes the specific packaging/ RoHS lead-free option and related temperature range per TI’s catalog.
If you need exact electrical specs (voltage ranges, propagation delay, drive strength) or recommended applications, the datasheet is the best reference.

Features

Key features of 74AVC4T3144GU12X:
- 4-bit bidirectional voltage-level translator/buffer
- Automatic direction sensing between A-side (VCCA) and B-side (VCCB) rails
- Dual-supply I/O for translating between two voltage domains
- 3-state outputs with enable (OE) control
- Ioff for partial-power-down/no back-powering protection
- ESD protection on all I/O pins
- Low-power high-speed CMOS technology
- RoHS-compliant, small 16-pin package (GU12X) suitable for compact designs

Package

The 74AVC4T3144GU12X is supplied in a 12-pin UQFN/UDFFN (USON/SON-style) leadless micro-package — a compact, RoHS-compliant 12-pin green package commonly used for space-constrained logic ICs.

Pinout

- Pin count: 12 pins (U12 package).
- Function: 74AVC4T3144 is a 4-bit non‑inverting bus buffer/voltage‑level translator—four independent I/O channels for translating/ buffering signals between two voltage domains. It provides directionally defined buffering with an output‑enable control (tri‑state outputs) for bus interfacing and mixed‑voltage logic level translation.

Manufacturer

Manufacturer: Nexperia.
What kind of company: Nexperia is a Netherlands‑based global semiconductor company that designs and manufactures discrete components, logic ICs (including 74‑series devices), MOSFETs, diodes and power-management/analog products for automotive, industrial, and consumer markets; it was spun out of NXP in 2017.

Application

Applications of 74AVC4T3144GU12X include:
- Level shifting between mixed-voltage domains (e.g., 1.8/2.5V to 3.3V/5V)
- 4-bit data/address/control bus buffering and driving
- Tri-state bus switching for interfacing MCUs/GP I/O with memories, FPGAs, and peripherals
- Backplane/interconnect buffering in consumer and industrial systems
- General-purpose I/O expansion in mixed-voltage designs

Equivalent

Direct equivalents: SN74AVC4T3144 (Texas Instruments), 74AVC4T3144 versions from Nexperia, ON Semiconductor and Diodes Inc. — all pin‑ and function‑compatible 4‑bit AVC level‑translators. No other 74xx family part is a guaranteed drop‑in; consider other 4‑bit AVC/LVC translator parts from the same family if needed.
