SN74HC74ADBR

Flip Flops Overview

The SN74HC74ADBR is a dual D-type flip-flop from the Texas Instruments SN74HC74 series, housed in a 14-SSOP package. It features positive-edge triggering with independent set and reset inputs. The device operates on a supply voltage range of 2 V to 6 V. Key electrical parameters include a maximum propagation delay of 30 ns at 6 V and 5.2 mA output drive current. It supports a wide operating temperature range from -40°C to +85°C.

Flip Flops Feature Summary

• Dual D-type flip-flops with positive-edge clock triggering
• Independent active-low set and reset inputs for direct control
• CMOS Schmitt-trigger inputs for noise immunity
• Wide operating voltage range supporting 2 V to 6 V systems

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register construction
• Timing and control logic applications
• General-purpose storage elements in digital systems

Flip Flops Procurement Notes

Verify the specific ordering suffix 'A' corresponds to the SSOP package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to procurement. Ensure the component matches the required pinout and thermal specifications for the target application environment.

Flip Flops Selection Notes

Select this component for designs requiring dual edge-triggered storage within a compact surface-mount footprint. Consider the 2 V to 6 V supply range compatibility with system power rails. Evaluate the 30 ns propagation delay against system timing requirements. Verify that the 14-SSOP package dimensions fit the PCB layout constraints.

Flip Flops Part Context

This part belongs to the SN74HC74 family of high-speed CMOS logic devices. It provides two independent D-type flip-flops in a single integrated circuit. The HC series offers fast switching speeds and low power consumption compared to older logic families. The device is designed for general-purpose digital logic applications requiring reliable data storage and transfer.

Flip Flops Replacement Considerations

Compatible substitutes include SN74HC74N (PDIP package) and SN74HC74DR (SOIC package). Cross-reference pinouts and electrical characteristics before substitution. Ensure the alternative part number meets the same voltage and temperature specifications.
