CY74FCT823ATQCT

Overview

The CY74FCT823ATQCT is a nine-bit D-type flip-flop bus driver manufactured by Texas Instruments, belonging to the FCT logic series. It features tri-state, non-inverted outputs and accepts TTL input levels. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports surface mount installation in a 24-pin SSOP or QSOP package. It exhibits a maximum propagation delay of 12.5 ns at 5 V with a 300 pF load and maintains an operating temperature range from -40 °C to +85 °C.

Feature Summary

• Integrates nine D-type flip-flops configured as a bus driver with master reset functionality.
• Provides tri-state, non-inverting output capability for efficient data bus management.
• Ensures high-speed signal transmission with low propagation delay characteristics.

Applications

• High-performance data bus buffering and driving applications
• Clocked memory interface circuits requiring reliable data latching
• General-purpose digital logic systems utilizing TTL-compatible inputs

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and tape/reel specifications. Ensure the component matches the required moisture sensitivity level and lead-free status for your assembly process. Cross-reference the manufacturer part number with authorized distributors to confirm current availability and authenticity before procurement.

Selection Notes

Select this component when a nine-bit width is required for bus drivers with registered outputs. Consider the FCT series compatibility with existing TTL logic families. Evaluate the 24-pin SSOP/QSOP footprint constraints against available PCB space. Confirm that the 12.5 ns delay meets system timing requirements under expected capacitive loads.
