74LCX162374MTDX

Overview

The Fairchild Semiconductor 74LCX162374MTDX is a 16-bit D-type flip-flop with 3-state outputs, part of the LCX low-voltage CMOS logic family. It operates within a supply voltage range of 2.0V to 3.6V and features 5V tolerant inputs and outputs for seamless interfacing with 5V systems. The device is housed in a 48-pin TSSOP package and supports high-speed operation with a maximum propagation delay of 4.5ns at 3.3V. Designed for low power dissipation, it includes patented noise reduction circuitry and supports live insertion applications.

Feature Summary

• Provides 16-bit data storage with independent 3-state output control for bus-oriented transmission
• Features 5V tolerant I/Os allowing direct interface between 2.5V/3.3V logic and 5V environments
• Incorporates advanced CMOS technology for high-speed performance while maintaining low power consumption
• Supports live insertion and withdrawal operations without damaging the device or system

Applications

• High-density memory address buffering and clock distribution
• Bus-oriented transmitter/receiver circuits in portable electronic devices
• Data storage interfaces requiring 5V tolerance in low-voltage systems
• Wireless communication equipment and handheld terminals

Procurement Notes

Verify the specific suffix 'MTDX' against the official ON Semiconductor datasheet to confirm the tape-and-reel packaging configuration. Ensure the component matches the RoHS compliance status and moisture sensitivity level specified in the latest revision. Cross-reference the manufacturer part number with ON Semiconductor records, as Fairchild products are now managed under the ON Semiconductor portfolio.

Selection Notes

Select this component when designing systems that require 16-bit parallel data latching with tri-state capability. It is suitable for applications needing 5V tolerance on both inputs and outputs while operating from a single 2.0V to 3.6V supply. Consider the 48-TSSOP package for surface-mount assembly constraints and verify that the 4.5ns propagation delay meets the timing requirements of the target bus architecture.

Part Context

This device belongs to the 74LCX series, which utilizes advanced CMOS technology to deliver high-speed operation with low static power dissipation. The LCX family is designed to replace older 74HC and 74HCT logic families in low-voltage applications. As part of the ON Semiconductor portfolio following the Fairchild acquisition, these components maintain compatibility with standard logic interfaces while offering improved electrical characteristics for modern portable electronics.

Replacement Considerations

Check for equivalent parts such as the 74LCX162374MTC (tube) if reel packaging is not required. Verify pinout compatibility with other 16-bit transparent latches in the LCX family. Confirm that substitute components support the same 5V tolerant specifications and operate within the 2.0V to 3.6V voltage range.
