74HC73DB,118

Overview

The 74HC73DB,118 is a dual JK-type flip-flop logic integrated circuit manufactured by Nexperia. It operates within the HC logic series and utilizes CMOS technology. The component is housed in a 14-SSOP surface-mount package. It features two independent JK flip-flops with negative edge triggering. The device supports a supply voltage range from 2 V to 6 V. It includes dedicated clock (CLK) and preset (PRE) inputs for each flip-flop. The outputs are non-inverting Q and complement Q-bar terminals.

Feature Summary

• Dual JK flip-flop configuration with negative edge-triggered clocking
• CMOS construction ensuring low static power consumption
• Integrated asynchronous preset functionality for immediate state initialization
• Surface-mount packaging optimized for automated PCB assembly

Applications

• Digital data storage and register circuits
• Frequency division and counter logic design
• State machine implementation in control systems
• Shift register construction for serial-to-parallel conversion

Procurement Notes

Verify the specific ordering code 74HC73DB,118 against the manufacturer's current product database to confirm availability and lead times. Ensure that the requested quantity aligns with standard reel or cut-tape specifications provided by authorized distributors. Cross-reference the RoHS compliance status and environmental declarations prior to finalizing procurement orders to meet regulatory requirements.

Selection Notes

Select this component when designing circuits requiring dual independent JK flip-flops with negative edge triggering. The HC series offers high noise immunity suitable for general-purpose digital applications. Consider the 14-SSOP package dimensions for board space constraints. Verify that the operating voltage range of 2 V to 6 V matches the system power supply requirements.

Part Context

This part belongs to the Nexperia 74HC family of high-speed CMOS logic devices. The 74HC73 specifically denotes a dual JK flip-flop variant. It is designed for compatibility with standard TTL logic levels while offering improved switching speeds and lower power dissipation compared to older logic families. The DB suffix indicates the SSOP package type.

Replacement Considerations

Compatible substitutes include other manufacturers' dual JK flip-flops in SSOP-14 packages such as the SN74HC73N or equivalent JEDEC-standard parts. Ensure pinout compatibility and logical function equivalence before substitution. Verify that alternative components meet the same voltage and temperature specifications.
