74HCT112N,652

Overview

The 74HCT112N,652 is a dual JK flip-flop with set and reset functions, manufactured by NXP USA Inc. under the 74HCT series. It utilizes negative-edge triggering for data capture. The device operates within a supply voltage range of 4.5V to 5.5V. It features asynchronous set and reset inputs that allow direct control of the output states independent of the clock signal. The component is housed in a 16-pin DIP package, suitable for through-hole mounting. It complies with JEDEC standard no. 7A and offers ESD protection exceeding 2000V (HBM) and 200V (MM).

Feature Summary

• Dual JK flip-flop configuration with negative-edge clock triggering.
• Asynchronous active-low set and reset inputs for immediate state control.
• Compliant with JEDEC standard no. 7A for logic interface compatibility.

Applications

• Digital counting circuits requiring binary state storage.
• Sequential logic systems utilizing edge-triggered memory elements.
• Data register applications needing parallel load or shift capabilities.

Procurement Notes

Verify the specific suffix '652' against current Nexperia/NXP ordering codes, as packaging formats may vary. Confirm RoHS compliance status via the latest datasheet revision, as environmental declarations can change. Check for obsolescence notices or PCNs related to manufacturing site transfers. Ensure the DIP-16 package availability matches your PCB assembly requirements. Cross-reference the manufacturer part number with authorized distributor catalogs for accurate sourcing.

Selection Notes

Select this component when a dual JK flip-flop with asynchronous control is required in a through-hole design. The HCT logic family ensures TTL-compatible input levels while maintaining CMOS power consumption. Verify that the operating temperature range meets your application's environmental constraints. Consider the propagation delay specifications if timing criticality exists in your sequential circuit design. Ensure the supply voltage remains within the specified 4.5V to 5.5V window for reliable operation.

Part Context

The 74HCT112 belongs to the widely used 74HCT logic family, which bridges TTL and CMOS technologies. This specific variant provides two independent JK flip-flops in a single package, reducing board space compared to discrete solutions. The N,652 designation indicates a specific tube packaging format from NXP Semiconductors. It serves as a fundamental building block for complex digital systems requiring state retention and sequential processing capabilities.

Replacement Considerations

Equivalent parts include the 74HCT112D and 74HCT112PW from Nexperia, offering identical functionality in SO and TSSOP packages respectively. Other manufacturers such as Texas Instruments offer compatible alternatives like the SN74HCT112N. Verify pin compatibility and electrical characteristics before substitution. Ensure the replacement part supports the same asynchronous set/reset logic levels.
