74LCX32244G

Overview

The Fairchild Semiconductor 74LCX32244G is a low-voltage, 32-bit non-inverting buffer and line driver featuring three-state outputs. Designed for high-speed digital applications, it operates within a voltage range of 1.65V to 3.6V. The component utilizes a 96-pin FBGA package, providing compact integration for dense circuit designs. It serves as a memory address driver, clock driver, or bus transceiver in systems requiring signal buffering with minimal propagation delay.

Feature Summary

• Contains thirty-two non-inverting buffers with three-state outputs
• Designed for use as a memory and address driver
• Suitable for clock driver and bus-oriented applications

Applications

• Memory address driving
• Clock signal distribution
• Bus-oriented data transmission

Procurement Notes

Verify the manufacturer designation, as Fairchild Semiconductor's logic products are now managed under ON Semiconductor. Confirm the specific package variant matches the 96-FBGA configuration required for your PCB layout. Ensure the component meets RoHS compliance standards if mandated by your project specifications. Cross-reference the datasheet revision to confirm electrical characteristics align with your system requirements before finalizing procurement.

Selection Notes

Select this component when a high-density, low-voltage solution is needed for driving multiple lines simultaneously. The 32-bit width reduces board space compared to using multiple smaller buffers. Ensure the supply voltage falls within the 1.65V to 3.6V range. Consider the 96-FBGA package availability and soldering requirements during the design phase to ensure manufacturability.

Part Context

This part belongs to the LCX series of low-voltage CMOS logic devices. The LCX family is characterized by fast switching speeds and low power consumption, making it suitable for portable and battery-operated equipment. The 74LCX32244G specifically addresses the need for wide-bus buffering in modern digital systems where space and power efficiency are critical constraints.

Replacement Considerations

Public cross-reference documents list the SN74AS574DWE4 and DM74AS574WMX as related parts. Verify pin compatibility and electrical specifications carefully, as these alternatives may differ in package type, speed, or drive strength. Ensure any substitute maintains the 32-bit width and three-state output functionality required for the original design.
