MC74AC273MEL

Flip Flops Overview

The MC74AC273MEL is an octal D-type flip-flop manufactured by onsemi. It features eight edge-triggered D flip-flops with individual D inputs and Q outputs. The device includes a common buffered Clock (CP) input and a buffered, asynchronous Master Reset (MR) input to load and reset all flip-flops simultaneously. It operates within a supply voltage range of 2V to 6V. The component utilizes silicon gate CMOS technology and provides output current capabilities of 24 mA source/sink. It is housed in a 20-SOIC package.

Flip Flops Feature Summary

Flip Flops Procurement Notes

Verify the specific suffix 'MEL' against official onsemi documentation to confirm package dimensions and tape/reel specifications. Ensure compatibility with design-in requirements regarding operating temperature ranges and supply voltage limits. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and compliance with RoHS standards. Check for any recent product change notices affecting assembly or material composition.

Flip Flops Selection Notes

Select this component when an octal D-type flip-flop with high-speed CMOS performance is required. It is suitable for designs needing buffered clock inputs and asynchronous reset functionality. Consider the 24 mA output drive capability for direct interfacing with loads. Compare with the MC74AC374 if three-state outputs are needed instead of standard non-inverting outputs.

Flip Flops Part Context

This component belongs to the 74AC series of high-speed CMOS logic devices produced by onsemi. The 74AC family offers performance comparable to TTL but with lower power consumption and wider voltage operation ranges. The MC74AC273 specifically addresses the need for parallel data storage in digital systems requiring reliable edge-triggered operation.

Flip Flops Replacement Considerations

MC74AC374: Offers similar functionality but with three-state outputs instead of standard outputs.
