CD74FCT373TQM

Latches Overview

The CD74FCT373TQM is an octal transparent D-type latch manufactured by Harris Corporation, housed in a 20-pin QSOP package. It features tri-state outputs with a high output current capability of 64mA low and 15mA high. The device exhibits a typical propagation delay of 13ns. It operates as a single 8:8 circuit function, providing buffered inputs and common control for latch enable and three-state output enable.

Latches Feature Summary

• Octal transparent latching architecture with eight independent D-type storage elements
• Tri-state output configuration enabling direct bus line driving applications
• High drive strength outputs supporting significant load capacitance requirements
• Common control lines for simultaneous data latching and output state management

Latches Applications

• Parallel data buffering in digital communication systems
• Bus interface circuits requiring temporary data storage
• Memory address register implementations
• General-purpose logic data path control

Latches Procurement Notes

Verify the specific manufacturer origin, as Harris Corporation assets were acquired by other entities. Confirm the exact package variant matches the QSOP form factor. Ensure the component meets required RoHS compliance standards if applicable to your assembly process. Cross-reference the datasheet revision to confirm pinout consistency with existing designs.

Latches Selection Notes

Select this component when high-speed latching with substantial output drive is required. The FCT series offers faster performance than standard LS logic while maintaining CMOS power efficiency. Consider the 20-pin QSOP package constraints regarding board space and thermal dissipation. Verify voltage compatibility with the target system logic levels before integration.

Latches Part Context

This part belongs to the FCT (Fast CMOS Technology) family of logic devices. It serves as a functional equivalent to older bipolar transistor-transistor logic latches but utilizes modern CMOS fabrication. The device provides improved switching speeds compared to standard HC or HCT counterparts while retaining compatible input/output characteristics for many legacy designs.

Latches Replacement Considerations

Direct substitutes include the CD74HCT373 for similar functionality with different electrical specifications. Other FCT series variants may offer alternative packaging options. Verify pin compatibility and electrical parameters before substituting with components from different manufacturers within the same logical family.
