SN74HC273DWR

Flip Flops Overview

The SN74HC273DWR is an octal D-type flip-flop manufactured by Texas Instruments, belonging to the HC logic series. It features eight positive-edge-triggered D-type flip-flops with a common clock and master reset input. The device operates within a supply voltage range of 2 V to 6 V and supports surface-mount installation in a 20-SOIC package. Key electrical parameters include a propagation delay of 160 ns, a maximum clock frequency of 60 MHz, and static current consumption of 8 µA. Output drive capability is specified at ±5.2 mA, with an operating temperature range from -40°C to +85°C.

Flip Flops Feature Summary

• Contains eight independent D-type flip-flops sharing a single clock and master reset control line.
• Provides non-inverting outputs with standard CMOS drive characteristics.
• Includes built-in ESD protection mechanisms for enhanced reliability.

Flip Flops Applications

• Register applications requiring parallel data storage

Flip Flops Procurement Notes

Verify that the specific ordering suffix matches the required package type and tape/reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements against project standards. Ensure the component meets the necessary industrial temperature ratings for the intended operational environment before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when designing systems requiring multiple synchronized storage elements controlled by a single timing signal. The wide supply voltage range allows compatibility with various logic families. Consider the propagation delay and output current limits to ensure signal integrity and load driving capabilities meet circuit design constraints.

Flip Flops Part Context

This part belongs to the SN74HC273 family of octal D-type flip-flops. Variants exist in different packages such as TSSOP or DIP, and other logic families like AHC or HCT offer different speed and voltage characteristics. The DWR suffix specifically denotes the SOIC surface-mount package configuration used for automated assembly processes.

Flip Flops Replacement Considerations

• SN74HC273PW (TSSOP-20 package variant)
• SN74HC273N (DIP-20 package variant)

Flip Flops FAQ

How does the master reset function operate?

The master reset input forces all outputs low regardless of the clock or data input states when the signal is active low.

What is the trigger mechanism for the flip-flops?

The device uses positive-edge triggering, meaning data is latched into the outputs on the rising edge of the clock pulse.
