74ABT16373BDGG,512

Overview

The 74ABT16373BDGG,512 is a high-performance BiCMOS 16-bit transparent latch with 3-State outputs manufactured by NXP USA Inc. It integrates dual octal latches coupled to independent 3-State output buffers controlled by active-LOW Output Enable (nOE) and active-HIGH Latch Enable (nE) inputs. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from -40 °C to +85 °C. It features an output capability of +64 mA for low-level states and -32 mA for high-level states, ensuring robust drive performance for heavily loaded buses.

Feature Summary

• Dual octal transparent latch architecture with independent control gates for each section
• High output drive capability designed for heavily loaded 3-State buses and MOS memories
• Power-up 3-State function ensures safe initialization during power transitions
• ESD protection exceeding 2000 V per MIL STD 883 Method 3015

Applications

• Driving heavily loaded 3-State buses in digital systems
• Interfacing with MOS memories requiring high-speed data latching
• Connecting to MOS microprocessors via parallel data interfaces
• Applications requiring live insertion or extraction without bus contention

Procurement Notes

Verify the specific ordering suffix BDGG corresponds to the TSSOP48 package (SOT362-1) as defined in the official documentation. Confirm that the manufacturer designation aligns with current NXP Semiconductors product lines, as historical Philips branding may appear in legacy datasheets. Ensure compliance with the specified RoHS status and environmental classifications prior to integration into final designs.

Selection Notes

Select this component when a 16-bit transparent latch with high-current 3-State outputs is required for bus interfacing. The device is suitable for applications needing independent enable and output control for two octal sections. Consider the TSSOP48 package dimensions if space constraints require a thin shrink small outline footprint. Verify that the 4.5 V to 5.5 V supply voltage range matches the system power rails.

Part Context

This part belongs to the 74ABT series of high-performance BiCMOS logic devices. The 74ABT16373B variant specifically provides 16-bit latching functionality with 3-State outputs. It supersedes earlier versions such as the 74ABT16373B/74ABTH16373B data from February 1998. The device is designed to combine low static power dissipation with high speed and significant output drive capabilities.

Replacement Considerations

The datasheet indicates that this product replaces the 74ABT16373B and 74ABTH16373B specifications dated February 27, 1998. No other direct substitute part numbers are explicitly listed in the provided documentation.
