74LVTH373MTC

Latches Overview

The Fairchild Semiconductor 74LVTH373MTC is an octal transparent latch featuring three-state outputs, designed for bus-oriented systems. It operates within a supply voltage range of 2.7 V to 3.6 V and utilizes advanced BiCMOS technology to achieve high-speed performance comparable to 5V ABT logic while maintaining low CMOS power consumption. The device includes eight latches with non-inverting polarity and offers -32 mA output source current capability. Propagation delay is specified at 5 ns at 2.7 V and 4.5 ns at 3.3 V. It supports hot insertion and provides power-up/high-impedance states to prevent bus interference.

Latches Feature Summary

• Advanced BiCMOS technology enables high-speed operation similar to 5V ABT logic with low power consumption.
• Bus-hold data inputs eliminate the need for external pull-up resistors for unused inputs.
• Three-state outputs facilitate direct connection to bus structures in system applications.
• Supports hot insertion and maintains high-impedance state during power-up or power-down.

Latches Applications

• Bus-oriented system architectures
• Low-voltage (3.3V) memory mapping
• Interfacing between 3.3V logic and 5V TTL environments

Latches Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status via official documentation. Check for End-of-Life notices as availability may be restricted. Ensure storage conditions meet manufacturer specifications to maintain integrity.

Latches Selection Notes

Select this component for designs requiring octal latching with bus isolation capabilities. Verify that the 2.7V to 3.6V operating range aligns with the target system voltage. Consider the TSSOP-20 package constraints for PCB layout. Evaluate propagation delay requirements against system timing budgets.
