MM74HC273SJ

Flip Flops Overview

The MM74HC273SJ is an octal D-type flip-flop manufactured by onsemi, belonging to the HC logic series. It features eight independent positive-edge-triggered D flip-flops with non-inverting outputs in a single package. The device operates within a supply voltage range of 2 V to 6 V and supports surface-mount installation via a 20-SOP (SOIC) package. It exhibits a maximum propagation delay of 23 ns at 6 V with 50 pF load and maintains a low static current consumption of 8 µA. The component is rated for operation across a temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Integrates eight independent positive-edge-triggered D flip-flops for parallel data storage
• Provides non-inverting outputs compatible with standard CMOS logic levels
• Supports wide supply voltage operation from 2 V to 6 V for flexible system integration

Flip Flops Applications

• Parallel data storage registers in digital systems
• Shift register configurations for serial-to-parallel conversion
• Timing control circuits requiring precise edge-triggered state retention

Flip Flops Procurement Notes

Verify the specific suffix 'SJ' against official onsemi documentation to confirm package dimensions and tape/reel specifications. Ensure compatibility with existing PCB footprints for 20-SOP packages. Confirm RoHS compliance status through the manufacturer's environmental declaration prior to procurement.

Flip Flops Selection Notes

Select this component when designing systems requiring high-density octal storage within a limited footprint. The HC series offers speed-performance balance suitable for general-purpose digital applications. Consider the 2 V to 6 V operating range if the design utilizes varying voltage domains or requires robust noise immunity compared to lower-voltage alternatives.

Flip Flops Part Context

This part belongs to the widely adopted 74HC family of high-speed CMOS logic devices. The MM74HC273 variant specifically addresses the need for multi-bit memory elements in compact integrated circuit form factors. It serves as a fundamental building block for sequential logic designs in consumer electronics and industrial control systems.

Flip Flops Replacement Considerations

Cross-reference with MC74HC273ADWG for alternative packaging options such as TSSOP. Verify pinout compatibility with SN74HC273N from Texas Instruments for potential DIP-based legacy board upgrades.
