CD74HC112PW

Overview

The CD74HC112PW is a dual JK flip-flop integrated circuit manufactured by Texas Instruments, belonging to the 74HC logic family. It features two independent negative-edge-triggered JK flip-flops with preset and clear inputs in a 16-pin TSSOP package. The device operates within a supply voltage range of 2V to 6V and supports clock frequencies up to 60 MHz. Propagation delay is typically 30ns at 6V with 50pF load. It offers complementary outputs and low static power consumption.

Feature Summary

• Dual independent negative-edge-triggered JK flip-flops
• Active-low asynchronous preset and clear inputs
• Complementary outputs for each flip-flop
• Wide operating voltage range from 2V to 6V

Applications

• Parallel-to-serial data conversion circuits
• Frequency division and counting applications
• Shift register construction
• State machine implementation

Procurement Notes

Verify the package type matches the required TSSOP-16 footprint during procurement. Confirm the suffix 'PW' indicates the specific tube packaging variant. Ensure compatibility with the target PCB assembly process for surface-mount technology components.

Selection Notes

Select this component when dual JK functionality is required in a compact surface-mount form factor. Consider the 74HC series for standard CMOS performance. Evaluate the 2V to 6V operating range against system power constraints. Verify pinout compatibility if replacing legacy DIP packages.

Part Context

This part belongs to the Texas Instruments 74HC (High-speed CMOS) logic family. It is functionally equivalent to other 74HC112 variants but differs in packaging. The TSSOP package provides space savings compared to traditional DIP formats while maintaining electrical characteristics consistent with the broader 74HC series specifications.

FAQ

What is the trigger edge for the CD74HC112PW?

The flip-flops are triggered on the negative-going edge of the clock signal.

Does the CD74HC112PW have synchronous or asynchronous control inputs?

It features asynchronous preset and clear inputs that operate independently of the clock signal.
