CY74FCT823BTPC

Overview

The CY74FCT823BTPC is a single-element D-type flip-flop from the Texas Instruments FCT logic series, featuring nine bits of data storage. It utilizes positive edge triggering for clock synchronization and includes a master reset function. The device provides non-inverting outputs with three-state capability, allowing for bus-oriented applications. It operates within a supply voltage range of 4.75 V to 5.25 V and supports high drive currents of 32 mA (high) and 64 mA (low). The component is housed in a 24-pin PDIP package with a lead pitch of 0.300 inches (7.62 mm), designed for through-hole mounting.

Feature Summary

• Single-element D-type architecture with nine-bit parallel data storage capacity
• Positive edge-triggered clock input synchronized with master reset functionality
• Three-state non-inverting outputs enabling efficient bus interface management

Applications

• Bus-oriented memory register implementations
• Parallel-to-serial data conversion circuits
• High-speed digital signal processing interfaces

Procurement Notes

Verify that the specific part number matches the required 24-pin DIP package configuration and through-hole mounting style. Confirm that the operating temperature range of -40°C to +85°C aligns with your environmental specifications. Ensure the power supply voltage remains strictly within the 4.75 V to 5.25 V limits to maintain signal integrity and prevent device damage during operation.

Selection Notes

Select this component when a compact, high-density nine-bit storage solution is required for systems utilizing the FCT logic family. Its three-state output feature makes it suitable for multiplexed bus architectures where multiple devices share common data lines. Consider the positive edge trigger characteristic for timing alignment with other system clocks and verify that the through-hole package fits the available PCB footprint constraints.

Part Context

This device belongs to the CY74FCT823T series of advanced Schottky logic components. It complements other FCT family members by providing dedicated storage functions rather than buffering or driving capabilities. The integration of nine bits in a standard 24-pin package offers a balance between pin count efficiency and data width, serving as a bridge between smaller octal registers and larger multi-byte memory arrays in mixed-signal designs.

Replacement Considerations

Cross-reference with CY74FCT823ATPC for identical functional specifications but potentially different manufacturing lot characteristics. Verify compatibility with CY74FCT823BTQ for quad-small-outline package variants if surface-mount space is limited. Ensure substitute parts maintain the same 4.75V–5.25V supply requirements and three-state output electrical characteristics.
