74ABT16373ADGGRE4

Overview

The SN74ABT16373ADGGRE4 is a 16-bit transparent D-type latch manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features non-inverting logic with three-state outputs. The device provides high drive capability, delivering low-level output currents up to 32 mA and high-level output currents of -32 mA. Propagation delay is specified at 5.4 ns when operating at 5 V. It is housed in a TSSOP-48 surface-mount package and supports an industrial operating temperature range from -40°C to +85°C.

Feature Summary

• Transparent data storage architecture allowing direct input-to-output transmission when enabled
• High-drive three-state outputs capable of driving bus lines directly
• ABT technology ensures fast switching speeds with reduced power consumption

Applications

• Parallel data buffering in high-speed digital systems
• Bus-oriented memory register implementations
• Clock domain crossing synchronization circuits

Procurement Notes

Verify the complete part number including the RE4 suffix against official Texas Instruments documentation to confirm specific tape-and-reel packaging configurations. Ensure compatibility with standard TSSOP-48 footprint designs during procurement planning. Cross-reference RoHS compliance status using current manufacturer declarations rather than distributor summaries.

Selection Notes

Select this component for applications requiring 16-bit parallel latching with significant load-driving capabilities. The ABT series offers superior speed compared to standard ALS or LVC families while maintaining CMOS compatibility. Verify that system power supplies remain strictly within the 4.5 V to 5.5 V window to ensure signal integrity and prevent excessive static current draw.

Part Context

This device belongs to the SN74ABT16373A family of 16-bit transparent latches. It shares functional similarities with other 16-bit logic ICs but distinguishes itself through ABT process technology. The ADGGR variant indicates a specific TSSOP-48 package configuration, while the RE4 suffix denotes reel-based manufacturing specifications.

Replacement Considerations

SN74ABT16373ADGGR is a verified equivalent offering identical electrical characteristics and pinout compatibility.
