CD74HC107EE4

Overview

The CD74HC107EE4 is a dual J-K flip-flop manufactured by Texas Instruments in the HC logic series. It features negative-edge triggering and an asynchronous reset input, housed in a 14-pin PDIP package. The device operates within a supply voltage range of 2 V to 6 V. Key electrical parameters include a maximum clock frequency of 60 MHz and a propagation delay of 29 ns at 6 V with 50 pF load. Output currents are rated at 5.2 mA for both high and low states. It functions across a temperature range of -55°C to +125°C.

Feature Summary

• Dual J-K flip-flops with negative-edge triggering
• Asynchronous reset functionality
• High-speed CMOS technology for balanced performance

Applications

• Digital data storage circuits
• Shift register implementations
• Frequency division applications

Procurement Notes

Verify the specific ordering suffix EE4 to ensure compliance with environmental standards and packaging requirements. Confirm that the PDIP-14 package aligns with your PCB footprint design. Cross-reference the manufacturer part number against official Texas Instruments documentation to validate authenticity and technical specifications before procurement.

Selection Notes

Select this component when dual independent J-K flip-flops with reset are required in a through-hole design. The HC series offers significant power reduction compared to LSTTL. Ensure the operating voltage falls between 2 V and 6 V. Consider the 60 MHz clock limit and 29 ns propagation delay for timing-critical designs.

Part Context

This part belongs to the CD74HC107 family of high-speed CMOS logic devices. It is functionally compatible with other HC series components but distinct from HCT variants due to voltage thresholds. The EE4 suffix denotes specific manufacturing and environmental attributes defined by Texas Instruments for this particular package configuration.

Replacement Considerations

CD74HC107N is a standard PDIP-14 variant. CD74HC107E is a SOIC-14 alternative. Verify pin compatibility and package dimensions before substitution.
