74LVC273AQ20-13

Overview

The Diodes Incorporated 74LVC273AQ20-13 is an octal D-type flip-flop featuring a clear input, manufactured in the LVC CMOS logic series. It operates within a supply voltage range of 1.65 V to 3.6 V and utilizes a QFN-20 surface-mount package. The device provides push-pull outputs with drive capabilities of 24 mA high and low. It exhibits a propagation delay of 4.1 ns at 3.3 V and functions reliably across an industrial temperature range from -40°C to +125°C.

Feature Summary

• Octal D-type configuration with dedicated clear functionality
• Low-voltage CMOS technology for efficient power operation
• Robust output drive strength suitable for bus driving

Applications

• Parallel-to-serial data conversion circuits
• I/O port expansion in embedded systems
• Register storage in microcontroller interfaces

Procurement Notes

Verify the specific suffix AQ20-13 against official Diodes Incorporated documentation to confirm the QFN-20 package variant and tape-and-reel specifications. Ensure that the ordering information matches the required moisture sensitivity level and RoHS compliance status defined in the current product datasheet before finalizing procurement orders.

Selection Notes

Select this component when an octal register with a global clear function is required in space-constrained designs. The QFN-20 package offers a compact footprint compared to traditional SOIC options. Consider the 4.1 ns propagation delay and 24 mA drive capability for high-speed digital signal processing applications operating between 1.65 V and 3.6 V.

Part Context

This part belongs to the 74LVC273 family of octal D-type flip-flops produced by Diodes Incorporated. The LVC series is characterized by its compatibility with 3.3 V and 5 V systems while maintaining low power consumption. The AQ20 designation specifically identifies the QFN-20 package variant within this logical family.

Replacement Considerations

Direct substitutes include the 74LVC273AT20-13, which shares identical electrical characteristics but utilizes a TSSOP-20 package instead of QFN-20. Verify pinout compatibility and thermal performance differences when swapping between these package types.
