SN74HC273ANSR

Flip Flops Overview

The SN74HC273ANSR is an octal D-type flip-flop manufactured by Texas Instruments. It features eight independent D-type flip-flops with a common clock and reset input, providing positive-edge triggering for data storage. The device utilizes high-speed CMOS technology compatible with standard TTL logic levels. Key electrical parameters include a supply voltage range of 2V to 6V, propagation delay typically around 10ns at 5V, and output drive capabilities suitable for interfacing with various digital circuits. It operates within a temperature range of -55°C to +125°C.

Flip Flops Feature Summary

• Octal configuration with eight independent D-type flip-flops sharing a single clock and reset line
• Positive-edge triggering mechanism ensures precise data capture on clock transitions
• High-speed CMOS technology provides compatibility with standard TTL logic levels

Flip Flops Applications

• Parallel-to-serial data conversion in communication systems
• Register storage for temporary data holding in microprocessor interfaces
• Shift register construction for sequential logic applications

Flip Flops Procurement Notes

Verify the 'SN' suffix indicates the standard plastic SOIC-20 package when sourcing replacements. Confirm the 'A' grade designation matches required operating temperature ranges for industrial or military environments. Ensure the 'N' designation aligns with lead-free RoHS compliance requirements specified in the manufacturer's ordering information.

Flip Flops Selection Notes

Select this component when an octal register with a global reset is required. Consider the HC series for general-purpose high-speed applications requiring TTL compatibility. Evaluate the SOIC-20 package constraints against PCB layout space. Verify that the 2V to 6V supply range accommodates the system's voltage rails without level shifting needs.

Flip Flops Part Context

This part belongs to the Texas Instruments SN74HCxx family of high-speed CMOS logic devices. The HC series is designed for low power consumption and wide voltage operation. As an octal flip-flop, it serves as a fundamental building block for complex digital systems requiring parallel data storage and synchronization across multiple bits simultaneously.

Flip Flops Replacement Considerations

Equivalent parts include the SN74HCT273N for strict 5V TTL compatibility and the SN74LVC273A for lower voltage operations.
