Overview
The HD74HC73FP-E is a dual J-K flip-flop from the HC/UH series, manufactured by Renesas Electronics. It features true outputs and is housed in a 16-pin PDSO (SOIC) package compliant with EIAJ standards. The device operates within a supply voltage range of 2V to 6V and supports a maximum operating frequency of 20 MHz. It functions reliably across an extended temperature range from -40°C to +85°C. Key electrical characteristics include a noise immunity of 30% of VDD and low power consumption typical of CMOS technology.
Feature Summary
- Dual independent J-K flip-flops with complementary true and complement outputs
- Negative-edge triggered operation for precise timing control
- Compatible with standard CMOS logic families for broad system integration
Applications
- Parallel-to-serial data conversion circuits
- Shift register configurations for digital signal processing
- Frequency division and counting applications
Procurement Notes
Verify the specific suffix against official Renesas documentation to confirm package type and environmental compliance. Ensure the ordering code matches the required pin configuration and moisture sensitivity level. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and current production status before procurement.
Selection Notes
Select this component when a dual J-K flip-flop with negative-edge triggering is required in a surface-mount SOIC package. It is suitable for designs needing compatibility with standard HC logic levels and operation within industrial temperature ranges. Consider the 16-pin footprint for PCB layout constraints.
Part Context
This component belongs to the Hitachi-derived HD74HCxx series, now managed by Renesas Electronics following the acquisition of semiconductor operations. The HC/UH series represents high-speed CMOS logic, offering performance comparable to LS-TTL but with lower power consumption. This specific part continues the legacy of reliable digital storage elements in modern embedded systems.
Replacement Considerations
Check for direct equivalents such as SN74HC73 or CD74HC73 from other manufacturers. Verify pinout compatibility and electrical specifications like propagation delay and output drive current before substitution.
