SN74HC273PWT

Flip Flops Overview

The SN74HC273PWT is an octal D-type flip-flop manufactured by Texas Instruments, belonging to the HC logic series. It features eight independent rising-edge triggered D-type flip-flops with a common clock and master reset input. The device utilizes CMOS technology for both inputs and outputs, providing non-inverting logic polarity. It operates within a supply voltage range of 2 V to 6 V and supports a propagation delay of 160 ns. The high-level output current is -5.2 mA, while the low-level output current is 5.2 mA. The component is housed in a TSSOP-20 package.

Flip Flops Feature Summary

• Contains eight independent D-type flip-flops with positive-edge triggering
• Features a common clock input and a master reset input for synchronized control
• Provides direct Q outputs for all flip-flops without inversion

Flip Flops Applications

• Register applications requiring parallel data storage
• Counter circuits utilizing shared clock synchronization
• State machine implementations needing simultaneous reset capability

Flip Flops Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature rating. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement decisions. Ensure the component meets the specific environmental requirements of the target application design.

Flip Flops Selection Notes

Select this component when an octal storage element with a shared reset function is required. Consider the TSSOP-20 package constraints regarding board space and thermal dissipation. Evaluate the 2 V to 6 V operating range against system power supply stability and noise margins.

Flip Flops Part Context
