74ABT16373CMTDX

Overview

The Fairchild Semiconductor 74ABT16373CMTDX is a 16-bit transparent D-type latch with 3-STATE outputs. It is designed for bus-oriented applications and features byte control logic. The device contains sixteen non-inverting latches where flip-flops appear transparent to data when the Latch Enable (LE) input is HIGH. Data meeting setup time requirements is latched when LE transitions LOW. Outputs are enabled onto the bus when Output Enable (OE) is LOW, entering a high impedance state when OE is HIGH.

Feature Summary

• Separate control logic for each byte
• High impedance glitch-free bus loading during power up and down cycles
• Non-destructive hot insertion capability
• Guaranteed latch-up protection

Applications

• Bus oriented system applications
• Memory address latching
• I/O port implementations

Procurement Notes

Verify that the suffix 'CMTDX' corresponds to the specific tape and reel packaging configuration required for automated assembly processes. Confirm that the component meets RoHS compliance standards as indicated by manufacturer documentation. Ensure the ordering part number matches the exact package type and temperature range specifications defined in the official datasheet to avoid functional mismatches.

Selection Notes

Select this component for designs requiring 16-bit data storage with byte-level control capabilities. The ABT series technology offers high-speed performance suitable for demanding bus architectures. Consider the separate enable inputs for managing complex data flow directions within multi-master systems.

Part Context

This component belongs to the 74ABT logic family, representing a 16-bit version of the octal 74ABT373 latch. It utilizes advanced Bipolar-CMOS-DMOS technology to provide high-speed operation while maintaining low power consumption. The device serves as a standard solution for temporary data storage in digital logic circuits.

Replacement Considerations

Cross-reference with Texas Instruments part numbers such as 74ABT16373ADGGRE4 or 74ABT16373ADGGRG4 for equivalent functionality from alternative manufacturers.
