9022DC

Overview

The National Semiconductor 9022DC is a JK-type flip-flop integrated circuit housed in a 16-CDIP package. It contains one element with two bits per element, operating on positive edge triggering. The device supports a supply voltage range of 4.75V to 5.25V and features a maximum clock frequency of 50MHz. Key electrical specifications include a maximum propagation delay of 35ns at 5V with 15pF load, output current capabilities of 16mA for both high and low states, and a quiescent current of 30mA.

Feature Summary

• JK-type flip-flop architecture with positive edge triggering mechanism
• Dual-bit configuration within a single functional element
• Standard TTL-compatible logic levels and drive currents

Applications

• Digital data storage circuits
• Frequency division networks
• Shift register implementations

Procurement Notes

Verify the manufacturer origin carefully, as National Semiconductor assets are now managed by Texas Instruments. Confirm the specific package variant matches the 16-CDIP requirement. Ensure the component grade aligns with your operational temperature range needs. Cross-reference the datasheet version to confirm pinout compatibility with existing designs.

Selection Notes

Select this component when a dual-bit JK flip-flop is required for synchronous digital logic applications. Consider the 50MHz clock limit and 35ns propagation delay for timing constraints. Evaluate the 16-CDIP package suitability for through-hole assembly processes. Verify power consumption requirements against the 30mA quiescent current specification.

Part Context

This part belongs to the standard logic family of flip-flops produced by National Semiconductor. It serves as a fundamental building block for sequential logic circuits. The device provides reliable state retention and transition control for digital systems requiring binary data handling capabilities.

Replacement Considerations

Check for direct equivalents from Texas Instruments following the acquisition of National Semiconductor assets. Verify pin-to-pin compatibility before substituting with other JK flip-flop variants.
