74AC151MTCX

Overview

The Fairchild Semiconductor 74AC151MTCX is an 8-input digital multiplexer housed in a 16-pin TSSOP surface-mount package. It operates on a single supply voltage ranging from 4.5V to 5.5V and supports an operating temperature range of -40°C to 85°C. The device provides both true and complementary outputs, with output current capabilities of 24mA for sourcing and sinking. It belongs to the AC logic series, designed for high-speed data selection applications.

Feature Summary

• Provides eight selectable input lines within a single integrated circuit package
• Delivers both true and complementary output signals simultaneously
• Features TTL-compatible inputs for broad interface compatibility
• Supports universal function generation using four logic variables

Applications

• High-speed digital data routing and selection systems
• Universal logic function generators utilizing four variables
• Parallel-to-serial data conversion circuits
• Address decoding and memory mapping configurations

Procurement Notes

Verify the specific manufacturer origin, as Fairchild Semiconductor operations have been integrated into ON Semiconductor. Confirm that the part number suffix corresponds to the correct tape-and-reel packaging format. Ensure compliance with RoHS standards and check for any updated nomenclature changes resulting from corporate system migrations.

Selection Notes

Select this component when an 8-channel multiplexer with differential true/complementary outputs is required at standard 5V logic levels. Consider the 16-pin TSSOP footprint for space-constrained surface-mount designs. Evaluate propagation delay specifications against system timing requirements to ensure signal integrity during high-speed switching operations.

Part Context

This device is part of the 74AC family of high-speed CMOS logic devices. It serves as a core component for managing multiple data sources in digital systems. The MTCX suffix indicates the specific thin-shrink small-outline package type and reel packaging configuration used for automated assembly processes.

Replacement Considerations

Compatible substitutes include the 74ACT151SC and other industry-standard 8-input multiplexers such as the SN54LS151 or CD74AC151. Verify pinout compatibility and electrical characteristics before substitution.
