74LCX16373G

Latches Overview

The Fairchild Semiconductor 74LCX16373G is a low-voltage 16-bit transparent latch featuring 5V tolerant inputs and outputs. It contains sixteen non-inverting latches with three-state outputs, designed for bus-oriented applications. The device operates within a supply voltage range of 2.0V to 3.6V. It utilizes a 54-pin FBGA package. The component supports high-speed performance suitable for memory mapping and I/O buffering in portable systems.

Latches Feature Summary

• Provides 5V tolerant input and output capabilities for mixed-voltage system interfacing
• Features three-state outputs to facilitate efficient bus-oriented data transfer
• Designed for low-power consumption in portable electronic applications

Latches Applications

• Memory mapping systems
• I/O buffering for portable devices
• Bus-oriented data storage applications

Latches Procurement Notes

Verify the specific suffix 'G' indicates lead-free and RoHS compliance status as per manufacturer documentation. Confirm the 54-pin FBGA package type matches the target PCB footprint requirements. Check current production status, as legacy Fairchild components may have discontinued or obsolescence notices. Ensure ESD handling protocols are followed during assembly due to CMOS sensitivity.

Latches Selection Notes

Select this component when a 16-bit wide latch with tri-state control is required for bus architectures. The 5V tolerance allows direct interfacing between 3.3V logic and 5V peripherals without level shifters. Consider the FBGA package constraints for board space and thermal management. Verify that the operating voltage range aligns with the system's power supply rails.

Latches Part Context

This part belongs to the 74LCX series of low-voltage CMOS logic devices. The LCX family is characterized by high speed and low power dissipation. The 16373 variant specifically provides 16-bit latching functionality. Fairchild Semiconductor, now part of onsemi, originally developed this logic family for consumer and industrial electronics requiring efficient data retention.

Latches Replacement Considerations

Check for equivalents from onsemi or other manufacturers offering 16-bit transparent latches in FBGA packages. Verify pin compatibility and electrical specifications such as propagation delay and drive strength. Ensure any substitute maintains 5V tolerance and three-state output capabilities.
