74F112SC

Flip Flops Overview

The Fairchild Semiconductor 74F112SC is a dual JK negative edge-triggered flip-flop housed in a 16-lead Small Outline Integrated Circuit (SOIC) package. It contains two independent high-speed JK flip-flops with Direct Set and Clear inputs. Synchronous state changes are initiated by the falling edge of the clock, while asynchronous set and clear functions operate independently of the clock signal.

Flip Flops Feature Summary

• Contains two independent high-speed JK flip-flops within a single integrated circuit
• Features direct set and clear inputs that force outputs to specific states asynchronously
• Synchronous triggering occurs at the voltage level of the clock's falling edge

Flip Flops Applications

• Digital data storage and register circuits
• Sequential logic control systems
• Frequency division and counter applications

Flip Flops Procurement Notes

Verify the ordering code suffix 'SC' corresponds to the 16-lead SOIC package configuration. Confirm the manufacturer source is Fairchild Semiconductor or authorized successor entities like onsemi. Ensure the component matches the specific pinout and electrical characteristics defined in the official datasheet DS009472 for accurate integration into designs requiring negative edge-triggered functionality.

Flip Flops Selection Notes

Select this component when dual independent JK flip-flops with asynchronous control are required. The negative edge-triggered operation suits designs where state transitions must align with clock falling edges. The SOIC package offers surface-mount compatibility for compact PCB layouts. Verify input setup and hold times relative to the clock edge to ensure reliable synchronous state changes without affecting the flip-flop during clock inactive states.

Flip Flops Part Context

The 74F112 belongs to the 74F series of high-speed TTL logic devices. This series is characterized by faster propagation delays compared to standard 74LS counterparts. The device provides complementary Q and Q outputs for each flip-flop, enabling versatile interfacing with other logic gates in complex digital architectures requiring precise timing control.

Flip Flops Replacement Considerations

Public confirmed substitute part numbers include 74F112SJ and 74F112PC. These variants offer identical logical functionality but differ in physical packaging, specifically using SOP or PDIP formats respectively. Ensure mechanical fit and pin compatibility before substituting.
