SN74ALVCH16373KR

Overview

The SN74ALVCH16373KR is a 16-bit transparent D-type latch with 3-state outputs manufactured by Texas Instruments. It operates from a supply voltage range of 1.65 V to 3.6 V and features a maximum propagation delay of 3.6 ns at 3.3 V. The device provides ±24-mA output drive capability at 3.3 V and incorporates bus hold on data inputs to eliminate the need for external pullup or pulldown resistors. It is housed in a 56-pin BGA Microstar Junior (GQL) package.

Feature Summary

• Operates within a wide voltage range of 1.65 V to 3.6 V
• Features active bus-hold circuitry on data inputs
• Provides high-impedance state via buffered output-enable input

Applications

• Implementing buffer registers
• Configuring I/O ports
• Bidirectional bus drivers
• Working registers

Procurement Notes

Verify the specific GQL package variant against current availability status, as this component may be subject to lifecycle changes. Confirm that the 56-pin BGA Microstar Junior footprint matches the target PCB design guidelines. Ensure compatibility with the required operating temperature range of -40°C to 85°C for the intended application environment.

Selection Notes

Select this component when designing systems requiring 16-bit latching with 3-state control within low-voltage logic families. It serves as an alternative to other ALVCH series devices like the SN74ALVCH16373DGGR, differing primarily in package type. Consider its ±24-mA drive strength for direct bus interfacing without additional interface components.

Part Context

This device belongs to the Texas Instruments Widebus family of logic ICs. It is designed specifically for low-voltage applications, supporting mixed-mode signal operations. The part number suffix KR indicates the specific BGA Microstar Junior package configuration used for high-density board layouts.
