CD74FCT162823ATMT

Overview

The CD74FCT162823ATMT is a dual D-type flip-flop with a 9-bit configuration, manufactured by Harris Corporation. It operates within a supply voltage range of 4.5 V to 5.5 V and features positive edge triggering. The device utilizes a 56-pin TFSOP package with a width of 0.240 inches (6.10 mm). It supports an operating temperature range from -40 °C to 85 °C and includes bus hold inputs to eliminate external pull-up resistors.

Feature Summary

• Dual D-type flip-flop architecture with 9-bit data storage capability
• Positive edge triggering mechanism for synchronous data capture
• Integrated bus hold inputs to remove the need for external pull-up resistors
• CMOS construction with 3-state output characteristics

Applications

• High-speed digital data storage systems
• Synchronous logic circuit design
• Bus interface applications requiring registered data holding

Procurement Notes

Verify component authenticity through official Harris Corporation channels or authorized distributors. Confirm that the part matches the specific ATMT suffix for the 56-TFSOP package. Check for RoHS compliance status as indicated in documentation, noting potential non-compliance for older manufacturing runs. Ensure storage conditions align with CMOS semiconductor handling standards to prevent electrostatic discharge damage prior to installation.

Selection Notes

Select this component when a compact dual 9-bit D-type flip-flop solution is required for high-speed synchronous applications. The FCT series offers fast propagation delays suitable for demanding timing constraints. Consider the 56-pin TFSOP footprint for PCB layout compatibility. Verify that the positive edge trigger aligns with the system clock polarity. Evaluate the bus hold feature benefits against existing pull-up resistor requirements in the design.

Part Context

This device belongs to the Harris FCT (Fast CMOS Technology) family, designed for high-performance logic applications. The CD74FCT162823ATMT specifically addresses needs for dense data registration in communication and computing hardware. Harris Corporation, now part of L3Harris Technologies, produced this component for industrial and commercial markets. The FCT series bridges the performance gap between standard TTL and advanced CMOS technologies.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Cross-reference with other Harris FCT series dual 9-bit flip-flops if pinout and electrical specifications match. Verify package dimensions and thermal characteristics before substitution.
