概要

Description

74AC245MTCX is an 8-bit bidirectional bus transceiver with tri-state outputs, part of the 74AC CMOS family. It provides two parallel data buses (A1–A8 and B1–B8) connected through eight 3-state buffers. A DIR input selects the data direction (A-to-B or B-to-A), while an active-low OE (often labeled G or ~OE) enables or tri-states both buses. When OE is deasserted, the selected direction is driven; when OE is asserted, outputs go high impedance. This device is used to buffer or isolate buses, connect a microcontroller to peripherals, or bridge buses within a system where the same voltage domain is used. The MTCX suffix denotes a specific package/temperature grade for this part; consult the datasheet for exact package type and electrical characteristics. In short, it’s a fast, reusable 8-bit bus transceiver ideal for flexible bus interfacing.

Features

Key features of 74AC245MTCX (8-bit bidirectional bus transceiver):
- Octal (8-bit) bus transceiver with 3-state outputs
- Two 8-bit buses: A and B
- DIR input selects data flow: A→B or B→A
- OE (output enable, active-low) disables/enables all outputs (tri-states when high)
- Non-inverting data paths
- High-speed CMOS (74AC family) with low power
- Wide supply range typical: Vcc 2.0 V to 5.5 V; TTL-compatible inputs
- Suitable for bus interfacing, data routing, and bus isolation
- Available in common packages (e.g., 20-pin DIP/SO/SMD variants; MTCX packaging denotes a specific reel/pack option)

Package

20-pin small-outline package (SOIC), the MTCX variant.

Pinout

- Pin count: 20 pins (20‑pin package, e.g., SOIC/DIP variants).
- Function: Octal bidirectional transceiver with 3‑state outputs. It has two 8‑bit buses (A0–A7 and B0–B7). Direction is controlled by DIR (A→B when DIR=0, B→A when DIR=1). Output enable (/OE, active low) turns the outputs on/off; when /OE is high, both sides are high-impedance. Data is non-inverting.

Manufacturer

- Manufacturer: ON Semiconductor (ON Semiconductor Corporation).
- Company type: American multinational semiconductor company that designs, manufactures, and sells integrated circuits and discrete components (logic, analog, power) for automotive, industrial, communications, and consumer markets.

Application

Applications areas of 74AC245MTCX:
- 8-bit bidirectional bus transceiver for CPU/memory and peripheral data/address buses
- Bus isolation and tri-state buffering on shared data lines
- Interface between different logic families or voltage levels
- High-speed data buffering to improve drive and signal integrity
- Backplane/system-bus buffering in computers, embedded controllers, PLCs
- Flexible bus routing controlled by DIR and OE for multi-device architectures
