概述

Description

MC74HCT541ADWG is an octal buffer/driver with 3-state outputs in the 74HCT family. It provides eight non-inverting data paths (A0–A7 to Y0–Y7) with a common output-enable input (G). When the output enable is active, the outputs follow the inputs; when not, all outputs go high impedance, enabling bus sharing. The device is TTL-compatible, uses high-speed CMOS, and typically runs from a 4.5–5.5 V supply. Common uses include buffering a data bus between a microprocessor/logic and memory or peripherals, increasing drive capability and fan-out, and isolating buses in multi-device systems. The ADWG suffix denotes the package/RoHS-compliant form (check the datasheet for the exact package type and temperature rating). For precise electrical specs—propagation delay, drive strength, leakage, and pinout—refer to the MC74HCT541ADWG datasheet from TI/ON Semiconductor.

Features

Here are the key features of MC74HCT541ADWG:
- Octal buffer/line driver with 3-state outputs (8 buffers)
- Non-inverting data path: A0–A7 to Y0–Y7
- One enable input (G) that is typically active LOW to tristate all outputs
- HCT technology: TTL-compatible input thresholds
- Single-supply operation: Vcc = 4.5–5.5 V
- High fan-out capability and standard CMOS timing
- Packages/grade indicated by ADWG variant; suitable for surface-mount or standard PCB use
- ESD protection and wide operating temperature for typical digital systems
(Provides a fast, eight-bit buffer with controlled tri-state outputs for interfacing TTL with CMOS logic.)

Package

20-pin wide SOIC package (gull-wing leads), RoHS-compliant.

Pinout

- Pin count: 20 pins (20-pin package)
- Function: Octal buffer/line driver with 3-state outputs (non-inverting). It buffers eight data inputs (A0–A7) to eight outputs (Y0–Y7) and uses an enable input (G) to place the outputs in high-impedance state when disabled.

Manufacturer

Manufacturer: ON Semiconductor (ON Semiconductor Corporation).
Company type: An American multinational semiconductor company that designs and manufactures integrated circuits and other semiconductor devices.

Application

- 8-bit buffer/driver with tri-state outputs for bus driving
- Buffers data/address lines between microprocessors, memory and peripherals
- Provides bus isolation and enables multi-device sharing on a common bus
- I/O expansion and level-matching between TTL/CMOS devices and buses
- Drives moderate-capacitance loads in high-speed digital systems
