SN74HC273NS

Flip Flops Overview

The SN74HC273NS is an octal D-type flip-flop with a clear input, manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and features non-inverting CMOS outputs. The device provides a propagation delay of 160 ns and supports output currents of ±5.2 mA. It is housed in a 20-pin PDIP package designed for through-hole mounting. The component functions across a temperature range from -40°C to +85°C.

Flip Flops Feature Summary

• Contains eight edge-triggered D-type flip-flops with independent data inputs and original code outputs.
• Features a common clock (CP) and master reset (MR) to control all flip-flops simultaneously.
• Includes built-in ESD protection circuits exceeding specified voltage thresholds.

Flip Flops Applications

• Register designs requiring parallel data storage
• Counter circuits utilizing shared clock signals
• State machine implementations

Flip Flops Procurement Notes

Verify the specific suffix 'NS' against official Texas Instruments documentation to confirm the exact package type and availability status. Ensure the selected variant matches the required through-hole mounting style and operating temperature range for the intended application environment.

Flip Flops Selection Notes

Select this component when an octal D-type flip-flop with a global clear function is required. It is suitable for applications needing high-speed logic operation within standard CMOS voltage ranges. Consider the PDIP-20 package constraints for board layout and thermal management requirements.

Flip Flops Part Context

Flip Flops FAQ

How does the master reset function operate?

When the MR input is low, all outputs are forced to a low state regardless of the clock or data input states.

What is the trigger mechanism for the data transfer?

Each D input state is transferred to its corresponding output on the rising edge of the clock pulse.
