CD74HC73M96

Overview

The CD74HC73M96 is a dual negative-edge-triggered J-K flip-flop manufactured by Texas Instruments. It belongs to the HC/UH series of high-speed CMOS logic devices and features complementary outputs for each flip-flop. The component includes an asynchronous reset input for both flip-flops, allowing independent control of their states. It is housed in a 14-pin SOIC package with a width of 0.154 inches (3.90mm). The device operates within a supply voltage range of 2V to 6V and supports a maximum clock frequency of 60 MHz. It functions reliably across an extended temperature range from -55°C to 125°C.

Feature Summary

• Dual negative-edge-triggered J-K flip-flops with complementary outputs
• Asynchronous reset inputs for independent state control
• High-speed CMOS technology compatible with standard CMOS outputs

Applications

• Data storage and register circuits
• Frequency division and counting applications
• State machine implementations

Procurement Notes

Verify the specific manufacturer source, as the CD74HC73M96 part number appears in listings from multiple vendors including Renesas and Harris. Confirm that the received component matches the intended electrical specifications and pinout for the Texas Instruments variant. Ensure the package type corresponds to the 14-SOIC format specified in official documentation before integration into the design.

Selection Notes

Select this component when a dual J-K flip-flop solution is required for synchronous digital logic designs. The HC series offers compatibility with standard CMOS logic levels and provides sufficient speed for general-purpose applications. Consider the operating voltage range and temperature requirements to ensure suitability for the target environment. Verify availability and lead times if sourcing from distributors other than the primary manufacturer.

Part Context

This component is part of the broader 74HC73 family of dual J-K flip-flops. Variants such as CD74HC73M96E4 and CD74HC73M96G4 exist, often indicating specific packaging or compliance configurations. The M96 suffix typically denotes a specific tape and reel configuration or manufacturing lot code rather than a functional difference. Understanding these suffixes is crucial for ensuring correct physical integration and supply chain management.

FAQ

What is the trigger mechanism of the CD74HC73M96?

The CD74HC73M96 utilizes a negative-edge-triggered mechanism, meaning the output state changes in response to the falling edge of the clock signal.

Does the CD74HC73M96 have an active-low or active-high reset?

The datasheet description indicates an asynchronous reset input. Standard 74HC73 devices typically feature an active-low reset, but verification against the specific manufacturer's datasheet is recommended for definitive logic polarity confirmation.
