74ABT16373BDL,112

Overview

The NXP USA Inc. 74ABT16373BDL,112 is a high-performance BiCMOS 16-bit transparent latch with 3-State outputs. It consists of two independent octal latches coupled to 3-State output buffers. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range of -40 °C to +85 °C. Propagation delays from data inputs to outputs are typically 2.5 ns at 5 V with 50 pF load. Output drive capability reaches +64 mA for low state and -32 mA for high state.

Feature Summary

• Dual octal architecture with independent control gates for each byte section
• Power-up 3-State functionality ensures safe bus initialization
• Supports live insertion and extraction without destructive hot swapping
• High ESD protection exceeding 2000 V per MIL STD 883 Method 3015

Applications

• Bus-oriented applications requiring byte-controlled data storage
• Driving heavily loaded 3-State buses
• Interfacing with MOS memories
• Connecting to MOS microprocessors

Procurement Notes

Verify the package designation SSOP48 (SOT370-1) matches the target PCB footprint. Confirm the ordering suffix 112 corresponds to the specific tape-and-reel quantity required. Check the product status as this datasheet represents Philips Semiconductors historical documentation; current availability may differ.

Selection Notes

Select this component when dual-byte transparency and high-speed performance are required in a single package. The ABT series offers superior speed compared to standard ABT variants. Ensure the design accommodates the multiple VCC and GND pins necessary to minimize switching noise during operation.

Part Context

This part belongs to the 74ABT16373B family of 16-bit transparent latches. It replaces earlier versions such as the 74ABT16373B/74ABTH16373B from 1998. The BDG variant utilizes a TSSOP48 package, while the BDL variant specifically uses the SSOP48 plastic shrink small outline package.

Replacement Considerations

Direct substitutes include other 74ABT16373B variants from different manufacturers or packages, such as the TSSOP48 version (74ABT16373BDGG). Verify pin compatibility and electrical characteristics before substitution.
