SN74HC112N

Flip Flops Overview

The SN74HC112N is a dual J-K negative-edge triggered flip-flop manufactured by Texas Instruments in the HC logic series. It operates within a supply voltage range of 2 V to 6 V and features asynchronous preset (/PRE) and clear (/CLR) inputs that override other inputs when active low. The device provides complementary outputs and supports clock frequencies up to 60 MHz with a typical propagation delay of 13 ns at 6 V. It utilizes a 16-pin PDIP package for through-hole mounting and maintains a maximum static current of 4 µA.

Flip Flops Feature Summary

• Contains two independent J-K flip-flops with negative-edge triggering on the clock input.
• Features asynchronous preset and clear functions activated by low-level signals.
• Supports operation across a wide voltage range from 2 V to 6 V.
• Provides complementary outputs suitable for driving multiple LSTTL loads.

Flip Flops Procurement Notes

Verify the specific ordering suffix against official Texas Instruments documentation to confirm package type and environmental compliance. Ensure the procurement channel sources genuine components matching the SN74HC112N designation. Cross-reference datasheet revisions to confirm pinout consistency and electrical characteristics before integration into final designs.

Flip Flops Selection Notes

Select this component for designs requiring dual J-K functionality with asynchronous control in a through-hole format. Verify that the system voltage remains within the 2 V to 6 V operational range. Confirm that the required clock frequency does not exceed the specified limits for the chosen supply voltage. Ensure PCB layout accommodates the 16-pin DIP footprint dimensions.

Flip Flops Part Context

Flip Flops FAQ

How do the asynchronous preset and clear inputs function?

Low-level signals on the /PRE or /CLR inputs immediately set or reset the output states, overriding the J, K, and clock inputs regardless of their current levels.

What is the trigger mechanism for the flip-flops?

The flip-flops are negative-edge triggered, meaning data from the J and K inputs is transferred to the outputs upon the falling edge of the clock pulse.
