74ALVCH16373ZQLR

Overview

The SN74ALVCH16373ZQLR is a 16-bit transparent D-type latch with 3-state outputs, part of the Texas Instruments Widebus family. It operates from 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. It is housed in a 56-pin Microstar Junior (7x4.5 mm) BGA package.

Feature Summary

• Provides 16-bit data storage with transparent latching functionality
• Features 3-state outputs for bus-driven applications
• Supports low-voltage operation within the 1.65 V to 3.6 V range
• Delivers high-speed performance with a maximum propagation delay of 3.6 ns

Applications

• High-density data buffering in portable electronics
• Bus-oriented memory mapping systems
• Parallel-to-serial conversion interfaces
• Low-voltage logic level translation circuits

Procurement Notes

Verify the specific suffix ZQLR corresponds to the 56-pin Microstar Junior BGA package configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure thermal management requirements are met for the specified operating temperature range during system design validation.

Selection Notes

Select this component when a 16-bit latch with 3-state outputs is required in a compact footprint. The Widebus family compatibility ensures ease of integration into existing high-density designs. Consider the 3.6 ns speed and 3.3 V drive strength for high-performance bus applications requiring low power consumption.

Part Context

This device belongs to the SN74ALVCH16373 series, designed for widebus applications requiring high density and speed. It complements other ALVCH family members by offering 16-bit capacity in a small BGA form factor, suitable for space-constrained mobile and computing platforms.

Replacement Considerations

Direct substitutes include other variants within the SN74ALVCH16373 family with compatible pinouts. Verify package equivalence for alternative BGA options such as the standard TSSOP-48 if footprint changes are permissible.
