MC74HC273AFELG

Flip Flops Overview

The MC74HC273AFELG is an octal D-type flip-flop manufactured by onsemi, belonging to the HC logic series. It features eight independent D flip-flops with a common clock and active-low asynchronous reset input. The device operates within a supply voltage range of 2.0 V to 6.0 V. Key electrical parameters include a propagation delay of 145 ns, a high-level output current of -7.8 mA, and a low-level output current of 7.8 mA. It supports single-ended inputs and outputs, housed in a 20-lead SOIC-J package suitable for surface-mount applications.

Flip Flops Feature Summary

• Contains eight D-type flip-flops sharing a common clock and reset control line
• Asynchronous active-low reset function for immediate data clearing
• Compatible with standard CMOS outputs and LSTTL outputs when pull-up resistors are used
• High noise immunity characteristics inherent to silicon-gate CMOS technology

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register configurations for data storage and transfer
• General-purpose digital logic buffering and latching
• Microprocessor interface systems requiring data synchronization

Flip Flops Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status as indicated in official documentation. Check for obsolescence notices or lifecycle changes prior to final design approval. Ensure packaging specifications match assembly requirements. Validate that the specific suffix corresponds to the desired reel or tape configuration.

Flip Flops Selection Notes

Select this component for designs requiring multiple synchronized data storage elements within a single integrated circuit. Consider the 2V to 6V operating range for compatibility with various logic families. Evaluate the 145 ns propagation delay against system timing requirements. Ensure the SOIC-J package footprint aligns with PCB layout constraints. Verify thermal performance within the specified -55°C to +125°C operating temperature range.

Flip Flops Part Context

This part belongs to the 74HC273 family of octal D flip-flops, widely used in digital electronics for temporary data storage. It serves as a fundamental building block for sequential logic circuits. The HC series offers high-speed operation with low power consumption, making it suitable for battery-powered and high-density digital systems. It replaces older LS273 devices while maintaining pinout compatibility.

Flip Flops Replacement Considerations

MC74HC273ADWG is a surface-mount alternative from onsemi with similar functionality but different package dimensions.
