74ABT16373BDL,118

Overview

The NXP USA Inc. 74ABT16373BDL,118 is a high-performance BiCMOS dual octal transparent latch with 3-State output buffers. It 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. The device features two independent sections, each containing eight D-type latches. Propagation delays are typically 2.5 ns for data inputs and 2.0 ns for enable inputs at 5 V. Output drive capability reaches +64 mA (LOW) and -32 mA (HIGH). Quiescent supply current is limited to 19 mA maximum.

Feature Summary

• Dual octal transparent latch architecture with independent control gates
• High output drive capability designed for heavily loaded buses
• Power-up 3-State outputs to prevent bus contention during initialization
• ESD protection exceeding 2000 V per MIL STD 883 Method 3015

Applications

• Bus-oriented applications requiring transparent latching
• Driving MOS memories
• Interfacing with MOS microprocessors

Procurement Notes

Verify the ordering suffix '118' against official manufacturer documentation to confirm specific packaging or tape-and-reel specifications. Ensure the component status matches current production requirements, as datasheets may indicate superseded versions. Confirm RoHS compliance and environmental certifications directly from the latest product data sheet before finalizing procurement decisions.

Selection Notes

Select this component when designing systems requiring high-speed data latching with significant output drive strength. The ABT series offers superior speed compared to standard CMOS logic while maintaining low power consumption. Verify that the system voltage aligns with the 4.5 V to 5.5 V operating range and that thermal management accommodates the specified quiescent current limits under maximum load conditions.

Part Context

This device belongs to the 74ABT family of high-speed BiCMOS logic ICs manufactured by Philips/NXP Semiconductors. It serves as a successor to earlier 74ABTH variants. The 74ABT16373B provides a standardized pinout for 16-bit latching operations, commonly used in legacy and modern digital systems requiring reliable data storage and bus isolation capabilities.

Replacement Considerations

The datasheet indicates it replaces the 74ABT16373B/74ABTH16373B of 1998. Verify pin compatibility and electrical characteristics if substituting other 74ABT16373 variants.
