74ABT16373CMTD

Overview

The Fairchild Semiconductor 74ABT16373CMTD is a 16-bit transparent D-type latch featuring 3-STATE outputs, designed for bus-oriented applications. It operates within a supply voltage range of 4.5V to 5.5V and supports a maximum operating frequency of 120MHz. The device utilizes a 48-pin TSSOP package with a width of 10mm. It provides high impedance glitch-free bus loading during power-up and power-down cycles, ensuring non-destructive hot insertion capability.

Feature Summary

• Byte-controlled architecture with separate control logic for each octal section
• High impedance glitch-free bus loading during entire power up and power down cycle
• Non-destructive hot insertion capability
• Guaranteed latch-up protection

Applications

• Bus oriented system applications
• Data storage in parallel-to-serial conversion circuits
• Memory address latching in computer systems

Procurement Notes

Verify the specific suffix 'CMTD' against official Fairchild documentation to confirm pinout compatibility and package dimensions. Ensure the component meets RoHS standards if required by your assembly process. Cross-reference the manufacturer part number with current distributor listings to confirm availability and authenticity before procurement.

Selection Notes

Select this component when a 16-bit transparent latch with byte-control functionality is required for high-speed bus applications. It serves as a 16-bit version of the ABT373, offering improved performance over standard AC/ACT families. Consider its 3-STATE output capability for efficient bus sharing in complex digital designs.

Part Context

This component belongs to the 74ABT logic family, known for high-speed operation and CMOS low power consumption. It is functionally similar to other 16-bit latches like the 74LVC16373A but operates at higher voltages and speeds. The device is intended for use in systems requiring reliable data latching with minimal bus loading effects.

Replacement Considerations

The 74ABT16373ADGGRG4 from Texas Instruments is a confirmed substitute part number with identical functional specifications.
