Overview
The CD74HC107E is a dual J-K flip-flop manufactured by Texas Instruments, belonging to the HC logic series. It features two independent negative-edge-triggered elements with reset functionality. The device operates within a supply voltage range of 2 V to 6 V and supports propagation delays up to 60 MHz. It utilizes a PDIP-14 through-hole package and functions reliably across an extended temperature range from -55 °C to +125 °C.
Feature Summary
- Dual negative-edge-triggered J-K flip-flops with integrated reset
- High-speed CMOS technology enabling operation up to 60 MHz
- Wide operating voltage range supporting 2 V to 6 V supplies
Applications
- Digital data storage and shift register circuits
- Frequency division and counting applications
- State machine implementation in digital systems
Procurement Notes
Verify the specific manufacturer part number against official Texas Instruments documentation to ensure authenticity. Confirm that the PDIP-14 package matches design requirements. Check RoHS compliance status as indicated in the datasheet. Ensure the component meets the specified electrical characteristics for the intended operating environment before integration.
Selection Notes
Select this component when dual J-K flip-flops with reset are required in high-speed digital designs. The HC series offers balanced propagation delay and significant power reduction compared to LSTTL. Consider the PDIP-14 package for through-hole mounting needs and verify compatibility with the system's voltage levels and temperature constraints.
Part Context
This component belongs to the Texas Instruments CD74HC family of high-speed CMOS logic devices. The HC series is designed to provide performance comparable to TTL while consuming significantly less power. The CD74HC107E specifically provides dual J-K flip-flops, distinguishing it from other logic gates or single-element flip-flops within the broader logic portfolio.
Replacement Considerations
Public confirmed substitute part numbers: CD74HC107N, CD74HCT107E.
