SN74LS273DW

Flip Flops Overview

The SN74LS273DW is an octal D-type flip-flop manufactured by Texas Instruments in the LS logic series. It features eight non-inverting outputs and a master clear input, triggered on the positive edge of the clock signal. The device operates within a supply voltage range of 4.75V to 5.25V. Key electrical parameters include a maximum propagation delay of 27 ns at 5V with 15pF load, a maximum operating frequency of 30 MHz, and a static current consumption of 27 mA. It provides an output drive capability of 8 mA and is housed in a 20-pin SOIC package.

Flip Flops Feature Summary

• Contains eight independent D-type flip-flops providing positive-edge triggering functionality
• Includes a dedicated master clear input for synchronous reset operations
• Features non-inverting outputs compatible with standard TTL logic levels

Flip Flops Applications

• Octal data storage registers
• Parallel-to-serial data conversion circuits
• General-purpose digital logic buffering

Flip Flops Procurement Notes

Verify the specific suffix 'DW' corresponds to the SOIC-20 surface-mount package configuration. Confirm that the component meets the required LS-TTL electrical specifications for your system design. Ensure compatibility with the intended operating temperature range of 0°C to 70°C before finalizing procurement decisions.

Flip Flops Selection Notes

Select this component when an octal register with a single master clear input is required. It is suitable for designs needing positive-edge triggered storage with standard TTL interface levels. Consider the 27 ns propagation delay and 30 MHz maximum frequency limits against your system timing requirements.

Flip Flops Part Context

This part belongs to the SN74LS273 family of octal D-type flip-flops. It shares functional similarities with other variants like the SN74LS273N but differs in packaging. The DW suffix specifically denotes the plastic small-outline package, distinguishing it from through-hole DIP options within the same logical family.

Flip Flops Replacement Considerations

SN74LS273N is a verified pin-compatible alternative offering identical logical function in a different package format.
