74HCT107N,652

Overview

The 74HCT107N,652 is a dual JK flip-flop integrated circuit manufactured by NXP USA Inc. It belongs to the 74HCT logic family, designed for high-speed CMOS operation with TTL-compatible inputs. The device features two independent JK flip-flops within a single package, utilizing a 14-pin Dual In-line Package (PDIP). It operates on a supply voltage range of 4.5 V to 5.5 V and supports bidirectional data handling through separate J and K inputs controlled by a clock signal. The component includes dedicated preset and clear terminals for direct state control, ensuring reliable synchronous operation in digital logic applications.

Feature Summary

• Dual independent JK flip-flop configuration
• TTL-compatible input levels for HCT series
• Synchronous operation with clock control
• Direct asynchronous preset and clear functionality

Applications

• Digital counting circuits
• Data storage registers
• State machine implementations
• Frequency division networks

Procurement Notes

Verify the specific suffix '652' against official NXP documentation to confirm the exact tape-and-reel or tube packaging variant intended for your assembly process. Ensure that the sourcing channel provides valid RoHS compliance certificates matching the current manufacturing standards. Cross-reference the manufacturer part number with the distributor's catalog to avoid confusion with similar 74HC variants that may differ in electrical characteristics or pinout compatibility.

Selection Notes

Select this component when a design requires dual JK flip-flops with TTL-level input compatibility. It is suitable for systems operating at standard 5V logic levels where noise immunity and speed are balanced. Consider the PDIP package constraints for through-hole mounting requirements. Evaluate the maximum switching frequency limits relative to your system clock to ensure timing margins are sufficient for reliable data capture and release operations.

Part Context

This component is part of the widely adopted 74HCT series, which bridges the gap between older TTL logic families and modern CMOS technologies. The 74HCT107 specifically addresses the need for dual flip-flops in compact packages. Its designation indicates it is a commercial grade device from NXP, optimized for general-purpose digital logic applications requiring robust performance and wide availability across various electronic systems.

Replacement Considerations

Compatible substitutes include the 74HC107N,652, though input thresholds differ slightly. Other manufacturers offer equivalent parts such as SN74HCT107N. Verify pinout compatibility and electrical specifications before substitution to ensure functional equivalence in existing designs.
