MC74F533DW

Overview

The MC74F533DW is an octal transparent latch manufactured by onsemi, belonging to the F/FAST logic series. It features eight D-type latches with inverted outputs and two common clock inputs. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a propagation delay of 9 ns at 5 V, a high-level output current of -3 mA, and a maximum operating temperature of +70 °C. It is housed in a 20-pin SOIC package.

Feature Summary

• Provides eight independent transparent latching channels for data storage applications
• Features inverted outputs suitable for direct interfacing with bus systems
• Utilizes common clock inputs to synchronize all eight latch stages simultaneously

Applications

• Parallel data buffering in digital communication interfaces
• Temporary data storage within microprocessor memory maps
• Signal synchronization between asynchronous logic domains

Procurement Notes

Verify the specific suffix 'DW' against official datasheets to confirm the SOIC-20 package variant and lead-free status. Confirm RoHS compliance details directly from the manufacturer's documentation. Ensure the component meets the required operating temperature range for your specific application environment before finalizing procurement.

Selection Notes

Select this component when designing circuits requiring eight-bit parallel data retention with inverted logic levels. The F/FAST series offers a balance of speed and drive capability appropriate for standard TTL loads. Verify that the 20-pin SOIC footprint aligns with your PCB layout constraints and thermal management requirements.

Part Context

This part belongs to the 74F533 family of octal latches produced by onsemi. It is functionally similar to other industry-standard octal transparent latches but is distinguished by its specific F-series performance characteristics and packaging options. The device serves as a fundamental building block for complex digital logic designs requiring multi-bit state retention.
