MM74HC273WM

Flip Flops Overview

The MM74HC273WM is an octal D-type flip-flop from onsemi's HC logic series, housed in a 20-SOIC surface-mount package. It features positive edge triggering and non-inverting outputs for eight independent bits within a single element. The device operates on a supply voltage range of 2V to 6V, with a maximum clock frequency of 78 MHz. Propagation delay is specified at 23ns under 6V supply and 50pF load conditions. It supports a wide operating temperature range from -40°C to +85°C and includes a master reset function.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops in a single integrated circuit
• Positive edge-triggered operation ensuring data capture on the rising clock transition
• Non-inverting output polarity delivering true logic states directly from the flip-flop inputs
• Master reset functionality allowing simultaneous clearing of all eight flip-flop outputs

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations for data storage and transfer
• Memory buffer stages in digital signal processing systems
• State machine sequencing and control logic applications

Flip Flops Procurement Notes

Verify the specific suffix 'WM' corresponds to the SOIC-20 tube packaging variant when sourcing. Confirm RoHS compliance status and REACH material declarations via official datasheets prior to integration. Ensure design compatibility with the 2V to 6V operating voltage range and check moisture sensitivity level requirements for surface mount assembly processes.

Flip Flops Selection Notes

Select this component for designs requiring high-density octal storage in a compact surface-mount footprint. Compare propagation delay specifications against system timing constraints, noting the 23ns value at 6V. Evaluate power consumption needs as static current is typically low, but consider switching currents during high-frequency operation up to 78 MHz for thermal management.

Flip Flops Part Context

This part belongs to the standard 74HC family of CMOS logic devices, widely used for general-purpose digital logic functions. The MM74HC273 variant specifically addresses applications needing multiple synchronized storage elements without external wiring complexity. It serves as a foundational building block for complex digital systems requiring reliable data latching and parallel output capabilities.

Flip Flops Replacement Considerations

• MM74HC273N (PDIP-20 through-hole equivalent)
• MM74HC273MTC (TSSOP-20 alternative package)

Flip Flops FAQ
