74LCX16244GX

Overview

The Fairchild Semiconductor 74LCX16244GX is a low voltage 16-bit buffer and line driver featuring non-inverting logic with three-state outputs. It operates within a supply voltage range of 2.3V to 3.6V and provides 5V tolerant inputs and outputs. The device supports an output drive current of 24mA at VCC 3.0V and exhibits a maximum propagation delay of 4.5ns. It utilizes patented noise and EMI reduction circuitry, ensuring high-speed performance while maintaining low power consumption with a maximum quiescent current of 10µA.

Feature Summary

• Provides five-volt tolerant input and output capabilities for mixed-voltage system interfacing
• Features nibble-controlled architecture allowing independent or combined 16-bit operation via separate three-state control inputs
• Incorporates patented noise and electromagnetic interference reduction circuitry for signal integrity
• Supports live insertion and withdrawal operations through power-down high-impedance states

Applications

• Memory address drivers in computer systems
• Clock distribution networks
• Bus-oriented transmitter and receiver circuits

Procurement Notes

Verify the specific suffix GX against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with RoHS directives if required by your assembly process. Cross-reference the part number with current Fairchild or ON Semiconductor product status pages to confirm availability and lifecycle stage before finalizing procurement plans.

Selection Notes

Select this component when designing low-voltage digital interfaces requiring 16-bit width and three-state bus management. The 5V tolerance feature makes it suitable for bridging 3.3V logic domains with legacy 5V peripherals. Consider the nibble-control capability if partial byte manipulation is necessary without affecting the entire data word.

Part Context

This device belongs to the LCX family of low-voltage CMOS logic products. It serves as a non-inverting counterpart to the 74LCX16240 inverter series. The technology is designed to replace older LVC or LVX devices where lower voltage operation and reduced power consumption are critical requirements for modern portable and embedded electronics.

Replacement Considerations

Equivalent parts include the ON Semiconductor MC74LCX16244G and National Semiconductor 54LCX16244. Verify pinout compatibility and electrical characteristics such as propagation delay and output drive strength before substituting.
