CD74FCT16823ATMT

Overview

The CD74FCT16823ATMT is a CMOS bus driver from the FCT series manufactured by Harris. It features two independent functions, each handling nine bits of data with true output polarity. The device utilizes a 56-terminal PDSO package and operates within a supply voltage range of 4.5 V to 5.5 V. It supports an operating temperature range from -40 °C to 85 °C. Key electrical characteristics include a propagation delay of 12.5 ns and a load capacitance of 50 pF. Outputs are three-state, and the component includes clear and clock enable functionality.

Feature Summary

• Features two independent nine-bit functions for parallel data transmission
• Incorporates clear and clock enable control mechanisms
• Provides true output polarity with three-state capability
• Utilizes bus hold inputs to eliminate external pull-up resistors

Applications

• Parallel data bus interfacing in high-speed digital systems
• Clock distribution networks requiring precise timing control
• Memory subsystem data buffering and driving
• Multiplexed data transmission applications

Procurement Notes

Verify the specific suffix 'ATMT' against official Harris documentation to confirm package type and tape-and-reel specifications. Ensure the component meets required RoHS compliance status as indicated in datasheets. Confirm that the manufacturer source aligns with current corporate entities following industry acquisitions. Validate pinout compatibility with target PCB footprints before integration.

Selection Notes

Select this component when designing systems requiring dual nine-bit bus drivers with integrated clock enable features. Consider the 12.5 ns propagation delay for timing-critical paths. Evaluate the 50 pF load capacitance against trace lengths and receiver inputs. The PDSO56 package requires appropriate surface-mount assembly processes. Verify thermal performance within the specified -40 °C to 85 °C operational range.
