SN74HC112D

Flip Flops Overview

The Texas Instruments SN74HC112D is a dual J-K flip-flop integrated circuit belonging to the 74HC logic family. It contains two independent negative-edge-triggered J-K flip-flops with complementary outputs, housed in a 16-SOIC surface-mount package. The device supports a wide operating voltage range of 2V to 6V and functions across an extended temperature range of -40°C to +85°C. Key electrical specifications include a maximum clock frequency of 60 MHz, a typical propagation delay of 13 ns, and output drive capabilities of ±4 mA at 5V. Static current consumption is typically 4 µA.

Flip Flops Procurement Notes

Verify the specific suffix 'D' indicates the 16-SOIC surface-mount package configuration. Confirm that the component meets RoHS3 compliance standards as documented by Texas Instruments. Ensure the supplier provides valid traceability for the active or obsolete status depending on the specific production batch requirements.

Flip Flops Selection Notes

Select this component when dual edge-triggered storage elements are required within a single package. The HC series offers low power consumption and high noise immunity suitable for general digital logic applications. Verify that the SOIC package footprint aligns with the target PCB layout constraints and thermal management requirements.

Flip Flops Part Context

This part belongs to the standard 74HC logic family, widely used for general-purpose digital switching. It serves as a fundamental building block for sequential logic circuits requiring memory states. The device complements other 74-series logic gates to form complex digital systems.

Flip Flops FAQ

How does the SN74HC112D handle asynchronous inputs?

The device features asynchronous preset (/PRE) and clear (/CLR) inputs. A low level on either input will set or reset the output regardless of the state of the J, K, or clock inputs.

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 output on the falling edge of the clock pulse.
