74LCX32244GX

Overview

The Fairchild Semiconductor 74LCX32244GX is a low voltage 32-bit buffer and line driver featuring five-bit inputs and outputs with 5V tolerance. It contains eight non-inverting buffers organized as four elements of four bits each, housed in a 96-FBGA package measuring 13.5x5.5 mm. The device operates at supply voltages between 2.3V and 3.6V, providing high-speed performance with a maximum propagation delay of 6.5 ns at 3.3V. It supports live insertion and withdrawal while maintaining CMOS low power dissipation.

Feature Summary

• Features 5V tolerant inputs and outputs for interfacing with 5V signal environments
• Implements patented noise and EMI reduction circuitry
• Supports live insertion and withdrawal operations
• Provides high-speed operation with low power dissipation

Applications

• Memory address driving
• Clock distribution
• Bus-oriented transmitter and receiver applications

Procurement Notes

Verify the specific suffix GX indicates the 96-FBGA package configuration. Confirm current production status as Fairchild Semiconductor products may have transitioned to ON Semiconductor. Ensure compatibility with 2.3V to 3.6V supply rails and 5V tolerant I/O requirements before procurement.

Selection Notes

Select this component when a 32-bit wide bus interface is required with 5V tolerance capabilities. It is suitable for systems operating at 2.5V or 3.3V that need to communicate with 5V logic levels. Consider the 96-FBGA package size constraints and the need for low power consumption in high-density designs.

Part Context

This part belongs to the LCX series of low voltage CMOS logic devices. It is functionally related to the 74LCX244 octal buffer but provides expanded 32-bit width capability. The device is fabricated using advanced CMOS technology to achieve high speed while maintaining low power dissipation standards typical of the LCX family.

Replacement Considerations

Public cross-reference data lists SN74LVC32244GKER as a potential alternative from Texas Instruments. Verify pinout compatibility and electrical specifications against the original datasheet before substitution.
