MC74AC157DT

Overview

The MC74AC157DT is a quad 2-input multiplexer manufactured by onsemi, belonging to the 74AC logic series. It features four independent data selectors housed in a 16-TSSOP surface-mount package. The device operates on a single power supply ranging from 2V to 6V and supports an operating temperature range of -40°C to 85°C. Electrical characteristics include output drive currents of 24mA for both high and low states. The component complies with RoHS3 standards and carries an MSL rating of 1.

Feature Summary

• Provides four independent 2-to-1 data selection channels within a single integrated circuit
• Features true (non-inverted) outputs that directly reflect the selected input state
• Includes an active-low output enable pin to control data transmission
• Supports wide voltage operation suitable for various digital logic environments

Applications

• Data routing between multiple sources and a single destination
• Selection of instruction or data words in microprocessor systems
• Configuration of parallel-to-serial data conversion circuits
• Implementation of address decoding logic in memory systems

Procurement Notes

Verify the specific suffix 'DT' corresponds to the TSSOP-16 package configuration required for your design. Confirm compliance with RoHS3 directives if environmental regulations apply to your manufacturing process. Ensure the operating voltage range aligns with your system's power supply specifications before integration.

Selection Notes

Select this component when a compact solution for multiple independent data paths is required. The AC series offers higher speed performance compared to standard HC variants. Consider the 16-TSSOP footprint constraints during PCB layout planning. Verify that the 24mA output drive capability meets the load requirements of downstream components.

Part Context

This part belongs to the 74AC family of high-speed CMOS logic devices produced by onsemi. It serves as a functional equivalent to industry-standard multiplexers but utilizes advanced CMOS technology for improved switching speeds. The device is designed for general-purpose digital applications requiring reliable signal selection across a wide voltage spectrum.
