MC74ACT273DT

Flip Flops Overview

The MC74ACT273DT is an octal D-type flip-flop from the onsemi 74ACT series, housed in a 20-pin TSSOP package. It operates within a supply voltage range of 4.5 V to 5.5 V. The device features single-ended inputs and outputs with non-inverting polarity. Key electrical parameters include a propagation delay of 11 ns, high-level output current of -24 mA, and low-level output current of 24 mA. It functions at positive edge triggering and supports surface-mount installation across an operating temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type storage elements within a single integrated circuit.
• Positive edge-triggered operation ensures data capture occurs specifically on the rising clock transition.
• CMOS technology enables compatibility with standard logic levels while maintaining defined drive capabilities.

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• General-purpose register banks for microprocessor interfaces
• State machine implementation in digital control systems

Flip Flops Procurement Notes

Verify the specific suffix 'DT' corresponds to the TSSOP-20 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or certified distributor declarations prior to integration. Ensure design specifications align with the 4.5 V to 5.5 V supply voltage constraints and thermal requirements for the intended operating environment.

Flip Flops Selection Notes

Select this component when an octal latch is required with ACT-series speed and drive characteristics. Compare against HC-series variants if lower power consumption is prioritized over switching speed. Verify that the TSSOP-20 footprint matches the PCB layout constraints and that the 5V logic level compatibility meets system interface requirements.

Flip Flops Part Context

This part belongs to the 74ACT family of high-speed CMOS logic devices. It serves as a fundamental building block for sequential logic designs requiring multiple bits of storage. The device complements other 74ACT components by providing reliable data retention and fast propagation delays suitable for synchronous digital applications.
