SN74S112AN3

Flip Flops Overview

The SN74S112AN3 is a dual J-K negative-edge-triggered flip-flop from Texas Instruments, belonging to the SN74S series. It features Schottky clamping diodes for high-speed operation and includes independent preset and clear inputs for each flip-flop. The device operates within a supply voltage range of 4.5 V to 5.5 V. It utilizes a 16-pin PDIP package with through-hole mounting. Key electrical characteristics include a propagation delay of 10 ns and low-level output current capability of 20 mA.

Flip Flops Feature Summary

• Dual J-K negative-edge-triggered flip-flops with independent preset and clear functions
• Schottky clamping diodes integrated for high-speed switching performance
• Standard TTL input and output logic levels compatible with existing systems

Flip Flops Applications

• High-speed digital data storage circuits
• Frequency division and counting applications
• Shift register construction in digital systems

Flip Flops Procurement Notes

Verify component status as obsolete or active through official Texas Instruments channels. Confirm package integrity and pin alignment against the 16-pin PDIP specification. Ensure compatibility with standard TTL logic families during integration. Request manufacturer documentation for any specific handling requirements associated with legacy components.

Flip Flops Selection Notes

Select this component for applications requiring fast switching speeds within the SN74S family. Consider the availability of separate preset and clear controls for precise state management. Evaluate the through-hole packaging suitability for prototyping or specific board layouts. Compare against other SN74 variants if speed or power consumption constraints differ.

Flip Flops Part Context

This part belongs to the Texas Instruments SN74S (Schottky) logic family, known for improved speed over standard TTL. The SN74S112 specifically provides two independent J-K flip-flops in a single package. It serves as a foundational building block for sequential logic design in digital electronics.

Flip Flops Replacement Considerations

The SN74S112AN is listed as obsolete. Potential substitutes include the SN74LS112AN for lower power applications or the SN74AS112AN for enhanced performance, subject to availability and pinout compatibility verification.
