PI74FCT573ATQ

Latches Overview

The PI74FCT573ATQ is an octal transparent latch manufactured by Diodes Incorporated under the Pericom brand. It features eight true outputs and operates within a supply voltage range of 4.75V to 5.25V. The device utilizes Fast CMOS technology, providing TTL-compatible input and output levels with extremely low static power consumption. It includes hysteresis on all inputs and supports an industrial operating temperature range from -40°C to +85°C. The component is housed in a 20-pin QSOP package.

Latches Feature Summary

• Octal transparent latch design with three-state outputs for bus-oriented applications
• Pin compatible with bipolar FAST Series devices while offering higher speed and lower power consumption
• TTL input and output levels with low ground bounce characteristics
• Industrial operating temperature range spanning -40°C to +85°C

Latches Applications

• Bus oriented applications requiring data latching
• Memory drivers
• Address drivers
• System clock drivers

Latches Procurement Notes

Verify the specific ordering suffix 'Q' corresponds to the 20-pin QSOP package configuration. Confirm that the 'A' speed grade meets the required propagation delay specifications for the target circuit. Ensure the component matches the intended logic family requirements and voltage levels before procurement.

Latches Selection Notes

Select this component when an octal transparent latch with three-state outputs is required for bus applications. Consider the PI74FCT573ATQ for designs needing pin compatibility with bipolar FAST Series devices but requiring improved speed and reduced power consumption. Verify that the 20-pin QSOP package fits the available board space and manufacturing capabilities.

Latches Part Context

This part belongs to the PI74FCT series of Fast CMOS logic integrated circuits produced by Pericom Semiconductor Corporation, now part of Diodes Incorporated. The series is designed to replace older bipolar logic families with faster, lower-power CMOS alternatives. The PI74FCT573 specifically functions as an octal transparent latch, distinct from registered variants or bus transceivers within the same product line.

Latches Replacement Considerations

The PI74FCT573ATQ is pin compatible with the bipolar FAST Series. For direct replacements within the FCT family, consider the PI74FCT573ATS (SOIC), PI74FCT573ATL (TSSOP), or other speed grades such as PI74FCT573CTQ or PI74FCT573DTQ if different performance characteristics are needed.
