概述

Description

The SN74AXCH4T245RSVR is an 8-bit bidirectional bus transceiver with 3-state outputs from Texas Instruments. It consists of two 4-bit buses (A and B) and uses a DIR input to select the transfer direction (A↔B) and an active-low /OE input to enable or disable all outputs (tri-state when /OE is high). This device is used to buffer or isolate two buses, transfer data in either direction, and allow multiple devices to share a common bus without contention. The SN74AXCH4T245 is part of TI’s AXC family, designed for high-speed, low-power CMOS operation; it is typically a single-supply device with compatibility across common logic levels. The “RSVR” suffix denotes packaging via Tape-and-Reel (TI’s standard shipping). For exact electrical specs (voltage range, input/output characteristics, drive strength, timing, and Ioff), refer to the datasheet. Typical applications include data buffering between microcontrollers, memory interfaces, backplanes, and bus interfacing where bidirectional data transfer is required.

Package

In SN74AXCH4T245RSVR, the package is a 20-pin VSSOP (Very-Small-Outline) package. The RSVR suffix indicates Tape-and-Reel packaging.

Pinout

- Pin count: 20 pins (20-pin package).
- Function: 4-bit bidirectional bus transceiver with 3-state outputs. It provides A0–A3 and B0–B3 data lines; data can transfer A↔B under control of DIR, and the outputs are enabled/disabled by OE (active low). Used for bidirectional data transfer between buses (and level shifting/isolation).

Manufacturer

Manufacturer: Texas Instruments (TI).
What kind of company: TI is a global American semiconductor company that designs and manufactures analog, mixed-signal, and embedded processing integrated circuits.

Application

Applications:
- Bidirectional data buffering between ICs and subsystems
- Interfacing between different voltage domains (level shifting)
- Bus isolation with tri-state buffering and OE/DIR control
- Backplane/interconnect and motherboard data paths
- Microprocessor/peripheral interfaces (memory such as SRAM/EEPROM, I/O)
- High-speed data paths in embedded systems needing controlled direction and 3-state outputs

Equivalent

Equivalent parts (functionally the same 4‑bit bidirectional bus transceivers with tri‑state outputs and dual‑supply translation) include:
- SN74LVC4T245 (TI)
- MC74LVC4T245 (ON Semiconductor)
- 74LVC4T245 (Nexperia)
- 74LVC4T245 (STMicroelectronics)
Note: verify VCCA/VCCB ranges, OE polarity, and packaging (RSVR is TI’s reel/packaging code) to ensure exact electrical and mechanical compatibility.
