SN74ABT273DWR

Flip Flops Overview

The SN74ABT273DWR is an octal D-type flip-flop from the Texas Instruments 74ABT logic family, housed in a 20-SSOP surface-mount package. It features positive-edge triggering and non-inverting outputs with a master reset function. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical specifications include a maximum propagation delay of 6.8 ns at 5 V with 50 pF load, high-level output current of -32 mA, and low-level output current of 64 mA. It supports a clock frequency up to 150 MHz and functions reliably across an operating temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type storage elements in a single integrated circuit
• Positive-edge triggered operation synchronized by a common clock input for simultaneous data capture
• High-drive capability with TTL-compatible inputs and strong sink/source output currents
• Master reset functionality allowing asynchronous clearing of all flip-flop outputs

Flip Flops Applications

• Parallel-to-serial data conversion circuits requiring high-speed shifting
• Register files and buffer stages in digital signal processing systems
• State machine implementations in complex logic control applications
• Data acquisition interfaces for capturing multiple input lines simultaneously

Flip Flops Procurement Notes

Verify the specific suffix 'DWR' corresponds to the SSOP-20 package and reel packaging format when sourcing. Confirm that the 4.5 V to 5.5 V supply requirement aligns with the target system's power rails. Ensure thermal management considerations are addressed for the surface-mount installation within the specified -40°C to +85°C operational range. Cross-reference the manufacturer datasheet for pinout compatibility and electrical characteristics prior to final procurement decisions.

Flip Flops Selection Notes

Select this component when high-speed switching and robust drive strength are required compared to standard HC or HCT families. The ABT series offers superior performance metrics including faster propagation delays and higher output currents suitable for demanding digital interfaces. Consider the SSOP package dimensions for PCB layout constraints. Evaluate the 5 V operating voltage against system power availability. This part is appropriate for designs needing octal storage with precise timing synchronization and reliable noise immunity in industrial environments.

Flip Flops Part Context

This device belongs to the Texas Instruments 74ABT logic family, which utilizes Advanced BiCMOS technology to combine the speed of bipolar transistors with the low power consumption of CMOS. The SN74ABT273 variant specifically provides octal D-type flip-flop functionality. It serves as a high-performance alternative to older LS or standard HC logic families, offering improved switching speeds and drive capabilities while maintaining compatibility with existing TTL and CMOS logic levels in mixed-voltage systems.
