CD74HC112M96

Overview

The CD74HC112M96 is a dual J-K negative-edge-triggered flip-flop from Texas Instruments, housed in a 16-pin SOIC package. It operates on a supply voltage range of 2 V to 6 V with a maximum clock frequency of 60 MHz. The device features asynchronous preset and clear inputs that override other logic states. Propagation delay is typically 30 ns at 6 V. It supports serial-to-parallel data transfer and includes set/reset functionality for reliable state control.

FAQ

How do the asynchronous preset and clear inputs function?

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

What is the trigger mechanism for the CD74HC112M96?

The flip-flops are triggered on the negative-going edge (falling edge) of the clock pulse, transferring data from the J and K inputs to the outputs.
