CD74FCT16373ATMT

Latches Overview

The CD74FCT16373ATMT is a dual 8-bit D-type transparent latch manufactured by Harris Corporation. It operates within a 4.5V to 5.5V supply voltage range and features three-state outputs. The device is housed in a 48-pin TSSOP package with a shrink pitch. It supports an operating temperature range from -40°C to +85°C. Key electrical characteristics include a maximum low-level output current of 64mA and a load capacitance of 50pF. The propagation delay at nominal supply is 8ns.

Latches Feature Summary

• Dual independent 8-bit D-type latching circuits
• Three-state output capability for bus driving
• Transparent latch operation mode

Latches Applications

• Parallel data storage in high-speed digital systems
• Bus interface buffering
• Register file implementations

Latches Procurement Notes

Verify the manufacturer origin, as Harris Corporation logic assets were acquired by Renesas Electronics. Confirm RoHS compliance status, as original Harris versions may not meet modern environmental standards. Check for obsolescence notices or product change notifications (PCN) related to assembly sites or marking changes. Ensure the specific suffix matches the required package and temperature grade.

Latches Selection Notes

Select this component when dual 8-bit latching with high drive capability is required. Compare propagation delay and output current specifications against system timing requirements. Verify package compatibility with PCB footprint designs. Consider end-of-life status and availability of alternative sources if long-term production is needed.
