概要

Description

The 74AVC4T245BZX is a 4‑bit bidirectional bus transceiver with two separate supply rails, used for level shifting between voltage domains. It has A-side I/Os (A0–A3) on VCCA and B-side I/Os (B0–B3) on VCCB. A direction input (DIR) selects data flow: A→B when DIR=0, or B→A when DIR=1. An output-enable (OE) puts all outputs in high impedance. It’s a CMOS, high‑speed buffer/translator with tri‑state outputs, suitable for connecting devices at different logic levels (e.g., 1.8V to 3.3V or 5V domains). Features typically include Ioff support (power-saving when supplies are off) and ESD protection.
Key uses: interconnecting microcontrollers, memories, or sensors across voltage domains, buffering or translating a shared parallel bus.
Package suffix BZX denotes a specific TI packaging variant. For exact electrical specs (VCCA/VCCB ranges, leakage, speed), consult the SN74AVC4T245BZX datasheet.

Features

Key features of the 74AVC4T245BZX (highlights):
- 4-bit bidirectional bus transceiver with tri-state outputs
- Dual-supply operation: separate A-side (VCCA) and B-side (VCCB) rails for level shifting between voltage domains
- Direction control (DIR) and output enable (OE) pins to select data flow and tri-state the buses
- I/O pins on both sides can drive data in either direction depending on DIR
- TTL/CMOS-compatible inputs; suitable for fast logic interfacing
- ESD protection on all I/O pins; robust for mixed-voltage systems
- Available in standard TI packaging with tape-and-reel options (suffix BZX)
Note: exact voltage ranges and timing depend on the specific device variant and package.

Package

I don’t have live datasheet access. Please tell me the manufacturer (e.g., Nexperia, TI) or allow me to look it up and I’ll confirm the exact package type for 74AVC4T245BZX.

Pinout

Pin count: 14 pins (common TSSOP/SSOP packages; other package variants exist).
Function: 4‑bit, dual‑supply non‑inverting bus transceiver/level translator (A0–A3 ↔ B0–B3) with direction control (DIR) and output‑enable (OE). It translates signals between VCCA and VCCB domains and provides three‑state outputs when OE is inactive.

Manufacturer

Manufacturer: Nexperia.
What kind of company: Nexperia is a global semiconductor manufacturer (spun out of NXP) that designs and supplies standard logic ICs, discrete components and MOSFETs for automotive, industrial and consumer electronics.

Application

Applications:
- Bidirectional level shifting between two voltage domains (e.g., 5V↔3.3V, 3.3V↔1.8V) for MCUs, FPGAs, ASICs, memories, sensors.
- Buffering/translation of parallel data and address buses in embedded systems.
- Safe bus sharing and I/O interfacing with tri-state outputs between devices at different Vcc levels.
- General-purpose I/O buffering/protection in consumer, industrial, and automotive electronics needing cross-voltage interfacing.

Equivalent

Direct equivalents (same function/footprint) include:
- TI: SN74AVC4T245 (same 4‑bit dual‑supply translator)
- Nexperia: 74AVC4T245 (original family)
- ON Semiconductor: MC74AVC4T245
- Diodes Inc. / other manufacturers offer 74AVC4T245 variants
Confirm package suffix, VCC range and direction-control pinout against datasheets before substitution.
