74LVCH16373AX4PA

Latches Overview

The 74LVCH16373AX4PA is a 16-bit transparent D-type latch manufactured by IDT. It features separate D-type inputs for each latch and three-state outputs designed for bus-oriented applications. The device supports mixed 3.3 V and 5 V environments, with inputs drivable from either voltage level. Outputs maintain high-impedance states when disabled, allowing up to 5.5 V application without damage. It includes bus-hold functionality on data inputs to eliminate external pull-up resistors. The component operates within a wide supply voltage range of 1.2 V to 3.6 V and complies with JEDEC standards.

Latches Feature Summary

• Five-volt tolerant inputs and outputs enable direct interfacing with 5 V logic systems.
• Bus-hold feature on data inputs removes the requirement for external pull-up or pull-down resistors.
• Three-state outputs facilitate efficient bus-oriented applications with controlled signal driving.
• Low inductance power and ground pins minimize noise and ground bounce during operation.

Latches Applications

• Mixed 3.3 V and 5 V logic system interfaces
• Bus-oriented data storage applications
• High-density memory address latching

Latches Procurement Notes

Verify the manufacturer designation matches Integrated Device Technology (IDT) rather than NXP Semiconductors, as both produce this part number variant. Confirm the specific suffix 'X4PA' corresponds to the intended package type and tape-and-reel configuration. Ensure the datasheet revision aligns with the required operating temperature range specifications for your design environment.

Latches Selection Notes

Select this component when designing systems requiring 16-bit data latching with mixed voltage compatibility. It is suitable for applications needing bus-hold capabilities to simplify circuit design by removing external resistors. Consider its low power consumption and high ESD protection ratings for robust performance in industrial or consumer electronics environments where signal integrity is critical.

Latches Part Context

This component belongs to the LVCH series of CMOS logic devices, characterized by low voltage operation and high speed. It is functionally similar to other 16-bit latches but distinguished by its specific pinout and bus-hold features. The device is part of a broader family of level-shifting and buffering solutions used in digital communication and data processing circuits.

Latches Replacement Considerations

The 74LVCH16373A is a compatible alternative from NXP Semiconductors. Verify pin compatibility and electrical characteristics before substitution. Other variants may lack the bus-hold feature or have different package options.
