SN74LS112AD

Flip Flops Overview

The SN74LS112AD is a dual J-K negative-edge-triggered flip-flop from the Texas Instruments SN74LS112A series. It features two independent circuits in a 16-pin SOIC-Narrow package. Key electrical parameters include a propagation delay of 19 ns, a clock frequency of 45 MHz, and an operating voltage range of 4.5 V to 5.5 V. Output currents are specified as -400 uA (high) and 8 mA (low). The device operates within a temperature range of 0°C to +70°C.

Flip Flops Feature Summary

• Dual independent J-K flip-flops with negative-edge triggering
• Integrated asynchronous preset and clear inputs for direct output control
• Complementary outputs (Q and Q-bar) for versatile logic interfacing

Flip Flops Applications

• Binary counter circuits
• Shift register implementations
• Frequency division stages

Flip Flops Procurement Notes

Verify the specific suffix 'AD' corresponds to the SOIC-Narrow-16 package and tube packaging when ordering. Confirm RoHS compliance status via the manufacturer's official documentation or product page, as environmental declarations may vary by production batch. Ensure the supplier provides valid traceability data for quality assurance purposes.

Flip Flops Selection Notes

Select this component for designs requiring LS-TTL logic levels with surface-mount assembly. Compare against SN74ALS112AD for improved speed performance if the 19 ns delay is insufficient. Verify that the 4.5 V to 5.5 V supply range aligns with the system power architecture before finalizing the bill of materials.

Flip Flops Part Context

This part belongs to the SN74LS112A family of dual J-K flip-flops. It is functionally similar to other variants like SN74LS112AN but differs in package type. The LS series offers standard switching speeds suitable for general-purpose digital logic applications where moderate performance is required.

Flip Flops Replacement Considerations

SN74ALS112AD is a documented substitute offering faster switching characteristics within the same package.
