MC74ACT273DWG

Flip Flops Overview

The MC74ACT273DWG is an octal D-type flip-flop manufactured by onsemi, belonging to the 74ACT logic series. It features a positive-edge triggered clock mechanism with non-inverting outputs and a master reset function. The device operates within a supply voltage range of 4.5V to 5.5V, drawing a maximum static current of 8 µA. It delivers high drive capability with output currents of ±24 mA. Propagation delay is specified at 11 ns under standard conditions (5V, 50pF load), supporting clock frequencies up to 200 MHz. It is housed in a 20-SOIC surface-mount package.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type storage elements within a single integrated circuit.
• Positive-edge triggering ensures data capture occurs precisely at the rising edge of the clock signal.
• High-current push-pull outputs capable of driving significant capacitive loads directly.
• Global master reset input forces all outputs to a low state independently of clock or data inputs.

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Register file implementations in digital systems
• Buffering and latching of parallel data buses
• Timing synchronization and pulse stretching applications

Flip Flops Procurement Notes

Verify the specific suffix 'DWG' corresponds to the SOIC-20 tube packaging variant when sourcing. Confirm RoHS compliance status via official manufacturer documentation prior to integration. Ensure design compatibility with 5V logic levels, as this component does not support lower voltage operation ranges found in HC or AC families. Cross-reference pinouts against legacy datasheets if replacing older variants.

Flip Flops Selection Notes

Select this component for designs requiring robust 5V CMOS performance with high drive strength. The ACT series offers faster switching speeds compared to standard HC logic while maintaining CMOS power efficiency. Consider the 20-SOIC package dimensions for PCB layout constraints. Evaluate thermal dissipation requirements based on total output current usage during active states.

Flip Flops Part Context

This part belongs to the widely adopted 74ACT family, designed for high-speed digital applications using 5V power supplies. It serves as a direct functional replacement for older TTL-based octal registers but utilizes modern CMOS technology for reduced power consumption. The 74ACT273 is a standard industry-compatible logic device used extensively in computing and telecommunications hardware.

Flip Flops Replacement Considerations

MC74ACT273MG is a similar octal D-type flip-flop from onsemi, though it utilizes a different SOEIAJ-20 package format. Verify pinout compatibility and physical footprint differences before substituting. Other manufacturers may offer equivalent parts under the 74ACT273 designation, but electrical characteristics should be validated against the original datasheet.
