SN74S112ADR

Flip Flops Overview

The SN74S112ADR is a dual J-K negative-edge-triggered flip-flop from Texas Instruments' 74S series. It features complementary outputs and includes dedicated clear and preset inputs for direct control. The device operates within a supply voltage range of 4.5 V to 5.5 V, with a typical propagation delay of 6 ns. Packaged in a 16-SOIC (0.154 inch, 3.90 mm wide) surface-mount configuration, it supports standard TTL input levels and provides high noise immunity characteristic of the Schottky logic family.

Flip Flops Feature Summary

• Dual negative-edge-triggered J-K flip-flops with complementary outputs
• Dedicated asynchronous clear and preset inputs for immediate state control
• Schottky technology ensures high switching speed and noise immunity
• Standard TTL-compatible input logic levels

Flip Flops Applications

• High-speed digital data storage and shift registers
• Frequency division and counting circuits
• Parallel-to-serial data conversion modules
• State machine implementation in industrial control systems

Flip Flops Procurement Notes

Verify component authenticity through authorized distributors or TI direct channels. Confirm package integrity and pin alignment upon receipt. Check date codes against project requirements. Ensure ESD-safe handling procedures are followed during storage and assembly. Review RoHS compliance status if environmental regulations apply to the final product deployment.

Flip Flops Selection Notes

Select this component when high-speed operation is critical compared to standard 74LS variants. Consider the SOIC package for automated surface-mount assembly processes. Evaluate power consumption constraints as S-series devices draw more current than LS types. Ensure voltage levels match the system's 5V logic domain. Verify that negative-edge triggering aligns with the system clock timing requirements.

Flip Flops Part Context

This part belongs to the Texas Instruments 74S (Schottky) logic family, known for superior speed-performance-to-power dissipation product factors. It serves as a successor to earlier 74 series logic, offering faster switching times suitable for demanding digital applications. The SN74S112A variant specifically addresses needs for reliable dual flip-flop operations in complex sequential logic designs.

Flip Flops Replacement Considerations

SN74S112AN: Pin-compatible through-hole alternative from the same manufacturer. SN74ALS112AD: Lower power consumption variant with similar functionality but different electrical characteristics. SN74LS112AN: Slower speed option with lower power draw, suitable for non-critical timing applications.
