CD74HCT107E

Overview

The CD74HCT107E is a dual J-K flip-flop manufactured by Texas Instruments, featuring negative-edge triggering and an asynchronous reset function. It belongs to the HCT logic series, designed for compatibility with standard TTL inputs while utilizing CMOS technology. The component is housed in a 14-pin PDIP package suitable for through-hole mounting. It operates within a supply voltage range of 4.5V to 5.5V and supports a wide operating temperature range from -55°C to 125°C.

Feature Summary

• Dual J-K flip-flop configuration with negative-edge clock triggering
• Asynchronous reset capability for immediate state control
• HCT logic series ensuring TTL input compatibility
• CMOS output structure providing low power consumption

Applications

• Digital data storage and register circuits
• Frequency division and counter applications
• State machine implementation in digital systems
• Pulse synchronization and timing control

Procurement Notes

Verify the manufacturer part number CD74HCT107E against official Texas Instruments documentation to ensure authenticity. Confirm that the device meets the required HCT logic specifications and PDIP package dimensions. Check for compliance with relevant environmental standards such as RoHS if applicable. Ensure the supplier provides valid traceability information for quality assurance purposes.

Selection Notes

Select this component when a dual J-K flip-flop with negative-edge triggering and asynchronous reset is required. The HCT series ensures compatibility with TTL logic levels, making it suitable for mixed-logic designs. Consider the through-hole PDIP package for prototyping or applications requiring mechanical robustness. Verify the operating temperature range meets the specific environmental requirements of the target application.

Part Context

The CD74HCT107E is part of the CD74HCT10x family of high-speed CMOS logic devices. This family offers performance comparable to standard LS-TTL but with lower power consumption. The device integrates two independent J-K flip-flops into a single 14-pin package, optimizing board space for complex digital logic designs requiring multiple storage elements.

Replacement Considerations

Compatible substitutes include other dual J-K flip-flops from the same HCT family, such as the CD74HCT109E, provided the triggering edge and reset functionality align with the design requirements. Ensure any replacement maintains the 14-pin PDIP form factor and HCT input compatibility.
