74LVC574AQ20-13

Overview

The 74LVC574AQ20-13 is an octal D-type flip-flop manufactured by Diodes Incorporated, featuring three-state outputs. It operates within a supply voltage range of 1.65 V to 3.6 V and supports surface mount installation in a QFN-20 package. The device exhibits a propagation delay of 3.8 ns at 3.3 V, with output drive capabilities of -24 mA for high level and 24 mA for low level. It functions reliably across an extended temperature range from -40 °C to +125 °C.

Feature Summary

• Provides eight synchronized data storage elements with independent D inputs and Q outputs controlled by a single clock signal.
• Features three-state outputs that allow direct connection to bus lines without additional interface hardware.
• Supports low-voltage CMOS logic levels compatible with 1.65 V to 3.6 V power supplies.

Applications

• Parallel-to-serial data conversion circuits
• Clock domain crossing synchronization
• Buffering of microcontroller I/O ports

Procurement Notes

Verify the specific suffix AQ20-13 against the manufacturer's current datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the QFN-20 footprint aligns with your PCB layout guidelines. Confirm RoHS compliance status through official documentation before finalizing procurement decisions.

Selection Notes

Select this component when an octal latch with three-state capability is required in a compact QFN-20 package. It is suitable for designs needing low propagation delay and operation within the 1.65 V to 3.6 V voltage range. Consider thermal performance and board space constraints associated with the QFN-20 form factor during integration.
