概述

Description

SN74AXC4T245RSVR is a 4-bit bidirectional bus transceiver with 3-state outputs and two separate supply rails for level shifting between two voltage domains.
Key points:
- 4 data lines: A1–A4 and B1–B4
- Direction control (DIR): selects data flow A→B or B→A
- Output Enable (OE): tri-states all outputs when inactive
- Dual-supply operation: VCCA and VCCB allow interfacing different logic levels
- Noninverting data path and fast CMOS performance
- Packaged in RSVR (tape-and-reel) for manufacturing
Ideal for interfacing components running at different voltages (e.g., microcontrollers, FPGA, memories) and for bus isolation in mixed-voltage systems.

Features

Key features of SN74AXC4T245RSVR:
- 4-bit bidirectional bus transceiver with 3-state outputs
- Direction control input (DIR) for A↔B data flow
- Output-enable input (/OE) to tri-state the I/O
- Ioff support for partial-power-down (no back-powering when Vcc is off)
- Wide supply range: 1.65 V to 3.6 V (AXC family)
- CMOS input thresholds; TTL-compatible at appropriate levels
- ESD protection on I/O pins
- Available in RSVR (tape-and-reel) package
Concise, high-level features suitable for bidirectional bus interfacing and level-compatible signaling.

Package

20‑pin RoHS‑compliant SOIC (D‑package); typically supplied in Tape & Reel.

Pinout

Pin count: 20 pins.
Function: 4-bit bidirectional bus transceiver with two 4-bit ports (A0–A3 and B0–B3), a direction control (DIR) to select transfer direction (A→B or B→A), and an output-enable that tri-states both sides when disabled.

Manufacturer

Manufacturer: Texas Instruments (TI).
What kind of company: TI is an American multinational semiconductor company that designs and manufactures analog and digital integrated circuits and embedded processors. It is one of the world's largest semiconductor producers.

Application

- Level shifting between voltage domains on a 4-bit bus
- Bidirectional buffering between MCUs, FPGAs, memories, and peripherals
- Bus isolation and I/O expansion in embedded systems
- Interfacing backplanes or shared data/address buses
- High-speed signaling in automotive, industrial, and consumer electronics requiring tri-state control and translation
