CD74FCT844AM

Latches Overview

The CD74FCT844AM is a D-Type Transparent Latch manufactured by Harris Corporation, belonging to the FCT series. It features a 9:9 circuit configuration with tri-state outputs and operates on a supply voltage range of 4.75V to 5.25V. The device is housed in a 24-SOIC package and supports an operating temperature range from -40°C to 85°C. It exhibits a propagation delay of 7.5ns and has one independent circuit channel.

Latches Feature Summary

• Transparent latch architecture allowing direct data passage when enabled
• Tri-state output capability for bus sharing applications
• Bus hold inputs eliminate the need for external pull-up resistors

Latches Applications

• High-speed data buffering in CMOS systems
• Parallel interface data storage
• Register files in microprocessor-based designs

Latches Procurement Notes

Verify RoHS non-compliant status and MSL level 3 handling requirements during procurement. Confirm package type is 24-SOIC and check for original Harris Corporation documentation to ensure authenticity. Ensure supply voltage matches 4.75V-5.25V specifications for proper operation.

Latches Selection Notes

Select this component for applications requiring transparent latching behavior with tri-state outputs in the FCT logic family. Consider the 7.5ns propagation delay for timing constraints. Verify compatibility with 5V CMOS logic levels and ensure thermal management suits the -40°C to 85°C operating range.
