SN74HC273DW

Flip Flops Overview

The SN74HC273DW is an octal D-type flip-flop from the Texas Instruments HC logic family, housed in a 20-pin SOIC package. It features non-inverting outputs and includes a master clear input. The device operates within a supply voltage range of 2 V to 6 V. Key electrical parameters include a propagation delay of 160 ns, with high-level and low-level output currents of -5.2 mA and 5.2 mA respectively. It supports surface-mount installation and functions across a temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Contains eight independent D-type flip-flops with positive-edge triggering
• Includes a dedicated master clear input for synchronous reset operations
• Provides non-inverting outputs compatible with standard CMOS interfaces

Flip Flops Applications

• Parallel data storage and buffering in digital systems
• Shift register configurations for serial-to-parallel conversion
• State machine implementation in control logic circuits

Flip Flops Procurement Notes

Verify the specific ordering suffix to confirm the package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements for your assembly process. Confirm that the operating voltage range aligns with your system design before procurement. Check for any recent product change notifications regarding manufacturing updates.

Flip Flops Selection Notes

Select this component when an octal storage element with moderate speed is required. The HC series offers balanced performance for general-purpose logic applications. Consider the SOIC-20 package for prototyping or PCB designs requiring through-hole or standard SMT compatibility. Evaluate power consumption needs as HC devices have higher static current than AHC variants.

Flip Flops Part Context

This part belongs to the SN74HC273 series of octal D-type flip-flops. It is distinct from latch variants like the SN74HC373 which feature tri-state outputs. The HC technology uses silicon gate CMOS for faster operation compared to older LS or ALS families while maintaining pin compatibility.

Flip Flops Replacement Considerations

SN74HC273DWR is a reel-packaged variant of the same logical function. SN74HC273PW offers the same logic in a TSSOP-20 package. CD74HC273M is a comparable alternative from another manufacturer.
