概述

Description

74AXP4T245BQX is an 8-bit bidirectional bus transceiver in the 74AXP family. It buffers data between two 8‑bit buses (A[7:0] and B[7:0]) with tri‑state outputs, allowing devices on either side to drive a shared bus. Direction is controlled by DIR (data can flow A→B or B→A), and an OE input enables or disables the outputs (three‑state when not enabled). This makes it useful for interfacing across voltage domains, isolating buses, or buffering a processor/memory/FPGA bus. The “BQX” suffix denotes the packaging and temperature variant for this device. For use, connect A and B to the two buses, drive DIR to select direction, and use OE to enable the transceiver when needed. Check the datasheet for exact voltage ranges, drive strength, and package/temperature options.

Features

Here are the key features of 74AXP4T245BQX (octal bidirectional bus transceiver):
- 8-bit bidirectional bus transceiver with 3-state outputs (A0–A7 to B0–B7).
- DIR input to select direction (A→B or B→A).
- Active-low OE input to enable/disable outputs (tri-state).
- Non-inverting data path with high-speed CMOS technology (AXP family).
- Low static and dynamic power consumption (high efficiency).
- TTL/CMOS-compatible input thresholds for easy interfacing.
- RoHS-compliant, package options typically in a 20-pin package (BQX variant).
- Suitable for bus buffering, microprocessor/memory interfaces, and peripheral buses.
- Wide operating voltage range and industrial temperature support (check datasheet for exact limits).
Note: For exact voltage ranges, temperatures, and timing specs, please consult the manufacturer datasheet.

Package

20-pin TSSOP (Thin Shrink Small Outline Package).

Pinout

- Pin count: 20 pins (typical for SN74AXP4T245BQX in its package).
- Function: 8-bit bidirectional bus transceiver with 3-state outputs. It transfers data between two 8-bit buses (A and B) controlled by a direction input (DIR) and an output-enable input (OE). When OE is asserted, data passes in the chosen direction; when OE is deasserted, both sides go high-impedance.

Manufacturer

- Manufacturer: Nexperia.
- What kind of company: A Dutch global semiconductor company that designs and manufactures standard discrete, logic, and MOSFET devices (a spin-off from NXP Semiconductors).

Application

74AXP4T245BQX is a 4-bit bidirectional bus transceiver with tri-state outputs and direction control. Typical applications:
- Level shifting and buffering between devices at different logic voltages (e.g., 1.2–3.3V MCU/FPGA to 5V peripherals)
- I/O expansion and bus isolation in embedded systems
- Inter-board/backplane data buses and tri-state bus sharing
- Memory-mapped I/O interfaces and peripheral data paths
- General-purpose data buffering in telecom/industrial equipment
