74LCX16244MEA

Overview

The Fairchild Semiconductor 74LCX16244MEA is a low voltage 16-bit buffer and line driver featuring non-inverting outputs with three-state control. It operates within a supply voltage range of 2.3V to 3.6V and provides 5V tolerant inputs and outputs, enabling safe interfacing between different logic families. The device utilizes advanced CMOS technology to achieve high-speed operation while maintaining low power dissipation. Designed for memory address drivers, clock drivers, and bus-oriented transmitter/receiver applications, it supports live insertion and withdrawal. Each nibble has separate three-state control inputs that can be shorted for full 16-bit operation.

Feature Summary

• Provides sixteen non-inverting buffers with three-state outputs designed for memory, address, and clock driving applications.
• Features 5V tolerant inputs and outputs, allowing direct interface with 5V signal environments despite lower supply voltages.
• Supports live insertion and withdrawal capabilities due to power-down high impedance states.
• Utilizes patented noise and EMI reduction circuitry to enhance signal integrity.

Applications

• Memory and address bus drivers
• Clock distribution circuits
• Bus-oriented transmitter and receiver systems

Procurement Notes

Verify the specific suffix 'MEA' against official Fairchild or ON Semiconductor datasheets, as standard listings often use suffixes like 'G' or 'MTCX'. Confirm package type and RoHS compliance status directly from the manufacturer's current documentation. Ensure the component matches the required operating temperature range and electrical specifications for your design.

Selection Notes

Select this component when interfacing low-voltage logic with 5V tolerant buses in high-density designs. Consider its 2.3V to 3.6V operating range and low quiescent current for power-sensitive applications. Verify that the nibble-controlled three-state functionality aligns with your bus architecture requirements. Check for equivalent parts from other manufacturers if supply constraints exist.

Part Context

This part belongs to the 74LCX series of low-voltage CMOS logic devices. It is functionally similar to the 74LCX16240 (inverting) and 74LCX32244 (32-bit). The device is manufactured using advanced CMOS technology optimized for low voltage operation. It is part of a broader family of bus drivers used in portable and battery-powered electronics.

Replacement Considerations

Equivalent parts include the ON Semiconductor MC74LCX16244 and Nexperia 74LCX16244. Verify pin compatibility and electrical characteristics before substitution. Note that some equivalents may have different packaging options or slight variations in propagation delay.
