SN74S112ANSR

Flip Flops Overview

The SN74S112ANSR is a dual JK-type flip-flop with preset and clear inputs, manufactured by Texas Instruments. It belongs to the standard 74S series of Schottky TTL logic devices. The component is housed in a 16-pin Small Outline Integrated Circuit (SOIC) package designed for surface-mount technology applications. It operates within a supply voltage range of 4.75 V to 5.25 V and supports a data rate up to 45 MHz. The device features negative edge triggering and provides complementary outputs. Key electrical specifications include a maximum propagation delay of 20 ns at 5 V with a 15 pF load, an output current capability of 8 mA low-level and 400 µA high-level, and a static current of 6 mA.

Flip Flops Procurement Notes

Verify that the ordering suffix 'SR' corresponds to the tape-and-reel packaging format rather than tube distribution. Confirm the SOIC-16 package dimensions match the target PCB footprint requirements. Ensure the manufacturer part number matches the specific Schottky TTL variant to avoid confusion with other logic families. Check RoHS compliance status against current regulatory standards for the intended market.

Flip Flops Selection Notes

Select this component when high-speed switching is required compared to standard 74LS series alternatives. Consider the surface-mount package constraint if space efficiency is critical. Evaluate the power consumption profile relative to system thermal limits. Compare propagation delay specifications against system clock frequencies to ensure signal integrity. Verify input compatibility with existing logic levels in the design chain.

Flip Flops Part Context

This part is a member of the Texas Instruments 74S family, known for improved speed over earlier 74 series variants. The SN74S112 specifically implements dual JK flip-flops, a fundamental building block for sequential logic. It serves as a surface-mount alternative to through-hole DIP packages, facilitating automated assembly processes in modern electronics manufacturing.

Flip Flops FAQ

What is the trigger type of the SN74S112ANSR?

The device utilizes negative edge triggering, meaning state changes occur on the falling edge of the clock signal.

Does the SN74S112ANSR have asynchronous control inputs?

Yes, it includes dedicated preset and clear inputs that operate asynchronously to set or reset the flip-flop states independently of the clock.
