MC74HC74ADR2

Flip Flops Overview

The MC74HC74ADR2 is a dual D-type flip-flop manufactured by onsemi, featuring independent Set and Reset inputs. It operates within a supply voltage range of 2.0 V to 6.0 V. The device provides complementary Q and Q outputs for each flip-flop. Data transfers to the output on the positive clock edge. Inputs are compatible with standard CMOS outputs and LSTTL outputs when pull-up resistors are used. It supports surface mount installation in a 14-SOIC package.

Flip Flops Feature Summary

• Dual D-type flip-flops with asynchronous Set and Reset controls
• Positive-edge triggered data transfer mechanism
• CMOS input compatibility with LSTTL interface support via pull-ups
• Complementary Q and Q outputs available per element

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register configurations
• Digital state storage elements
• Timing delay applications

Flip Flops Procurement Notes

Verify the specific suffix against official documentation, as 'R2' may indicate reel packaging or regional variants. Confirm RoHS compliance status and moisture sensitivity level prior to integration. Ensure the source document explicitly defines the electrical characteristics for this exact suffix to avoid functional mismatches.

Flip Flops Selection Notes

Select this component for designs requiring dual independent flip-flops in a compact surface-mount package. It is suitable for systems operating between 2V and 6V where CMOS and LSTTL interfacing is required. Consider propagation delay specifications if high-speed timing is critical.

Flip Flops Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices. It serves as a direct pinout-compatible replacement for LS74 equivalents while offering lower power consumption. The device is designed for general-purpose digital logic applications requiring reliable state retention.
