74HC112PW,112

Overview

The 74HC112PW,112 is a dual negative-edge triggered JK flip-flop manufactured by Nexperia USA Inc. It features individual J and K inputs, clock (nCP), asynchronous active LOW set (nSD) and reset (nRD) inputs, and complementary nQ and nQ outputs. The device operates within a supply voltage range of 2 V to 6 V and supports an operating temperature from -40 °C to +85 °C. It utilizes CMOS input levels and includes Schmitt-trigger action on the clock input for tolerance to slow rise/fall times.

Feature Summary

• Dual negative-edge triggered JK flip-flops with independent control
• Asynchronous active LOW set and reset inputs
• Schmitt-trigger action on clock input for noise immunity
• Complementary nQ and nQ outputs

Applications

• Digital state storage circuits
• Frequency division logic
• Shift register construction
• Counter circuit design

Procurement Notes

Verify component authenticity through authorized Nexperia distributors or official channels. Confirm package integrity and pin alignment upon receipt. Check datasheet revisions for any recent marking or electrical specification updates. Ensure static-safe handling procedures are followed during installation. Validate compatibility with existing system voltage levels before integration.

Selection Notes

Select this component for applications requiring dual JK functionality in a compact TSSOP-16 package. Consider the 74HCT112 variant if TTL-compatible input levels are required instead of CMOS. Evaluate the asynchronous set/reset requirements against synchronous alternatives. Verify that the operating temperature range meets environmental constraints. Assess power consumption needs relative to other logic families.

Part Context

This part belongs to the Nexperia 74HC series of high-speed CMOS logic devices. It is designed for general-purpose digital applications requiring reliable state retention. The 74HC112 provides a standard solution for implementing sequential logic functions in consumer electronics and industrial control systems where space efficiency and low power consumption are priorities.

Replacement Considerations

The 74HCT112PW,112 serves as a functional substitute with compatible pinout but requires TTL-level input signals. Other manufacturers offer equivalent dual JK flip-flops in similar packages; verify electrical parameters and timing characteristics carefully. Ensure replacement parts meet the same ESD protection and operating temperature specifications.
