Overview
The Renesas Electronics Corporation 74LS112FPEL-E is a dual JK flip-flop integrated circuit belonging to the standard LS logic series. It contains two independent JK flip-flops with complementary outputs, designed for high-speed digital applications. The component operates within a supply voltage range of 4.75V to 5.25V and features negative edge triggering. It supports preset and clear functions for direct control of output states. The device is housed in a 16-pin plastic DIP package, suitable for through-hole mounting on printed circuit boards.
Feature Summary
- Dual JK flip-flop architecture with complementary outputs
- Negative edge-triggered clock operation
- Independent preset and clear inputs for direct state control
Applications
- Digital data storage and register circuits
- Frequency division and counter networks
- Sequential logic control systems
Procurement Notes
Verify the specific manufacturer part number against official Renesas documentation to confirm compatibility. Ensure that the procurement channel provides valid traceability for electronic components. Confirm that the received units match the specified 16-pin DIP package and LS logic family characteristics before integration into designs.
Selection Notes
Select this component when a dual JK flip-flop with asynchronous set and reset capabilities is required. It is appropriate for designs utilizing standard TTL-compatible logic levels. Consider the 16-pin DIP package constraints for board layout and verify that the operating temperature range meets the environmental requirements of the target application.
Part Context
This component is part of the widely used 74LS112 family of dual JK flip-flops. It serves as a fundamental building block for sequential logic circuits. The 'FP' suffix typically indicates a specific plastic DIP package variant. As an LS (Low-power Schottky) device, it offers a balance between speed and power consumption compared to standard TTL counterparts.
Replacement Considerations
Compatible substitutes include the SN74LS112 from Texas Instruments and the HD74LS113FP from Renesas, provided pinout and electrical specifications are verified. Ensure that any replacement maintains the same logic family characteristics and package dimensions for direct interchangeability.
