MC74AC273DTR2

Flip Flops Overview

The MC74AC273DTR2G is an octal D-type flip-flop from the onsemi 74AC logic series, housed in a TSSOP-20 surface-mount package. It operates within a supply voltage range of 2 V to 6 V and supports a maximum clock frequency of 175 MHz. The device features non-inverting outputs with a propagation delay of 13 ns and provides output drive currents of ±24 mA. It functions over an industrial temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Provides eight independent D-type storage elements triggered by positive edge-sensitive clock signals
• Includes a dedicated master reset input for synchronous clearing of all flip-flops
• Delivers high-speed data transfer capabilities suitable for wide-bus applications

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• High-speed buffering and register stages in digital systems
• Data acquisition and storage modules

Flip Flops Procurement Notes

Verify the complete part number suffix, as 'MC74AC273DTR2' lacks the final 'G'. Official documentation lists 'MC74AC273DTR2G' as the standard RoHS-compliant variant. Confirm that the intended procurement matches the exact manufacturer designation to ensure component compatibility and regulatory adherence.

Flip Flops Selection Notes

Select this component when designing systems requiring an octal register with fast switching speeds and moderate drive strength. The 74AC series offers superior performance compared to older 74LS equivalents while maintaining CMOS power efficiency. Ensure the design accommodates the specified 2V to 6V operating range and thermal requirements.

Flip Flops Part Context

This device belongs to the MC74AC273 family of octal D-type flip-flops manufactured by onsemi. It shares functional characteristics with other variants like the MC74AC273DWR2G but differs in physical packaging. The TSSOP-20 form factor is designed for compact surface-mount assembly in modern electronic devices.

Flip Flops Replacement Considerations

The MC74AC273DWR2G serves as a direct pin-compatible alternative featuring the same logical functionality but utilizes a SOIC-WB-20 package instead of TSSOP-20.
