74F533SCX

Latches Overview

The Fairchild Semiconductor 74F533SCX is an octal transparent latch belonging to the F/FAST logic series. It features eight D-type inputs and corresponding inverted outputs, housed in a 20-pin SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical characteristics include a propagation delay of 9 ns at 5 V, a high-level output current of -3 mA, and a maximum operating frequency of 80 MHz. It supports surface mount installation and functions within a commercial temperature range of 0°C to +70°C.

Latches Feature Summary

• Provides octal data storage with transparent latch functionality for eight independent channels.
• Features inverted outputs suitable for bus interface applications requiring signal inversion.
• Utilizes F/FAST technology to achieve high-speed switching performance.

Latches Applications

• High-speed data buffering in digital systems
• Octal bus driver configurations
• Parallel-to-serial data conversion interfaces

Latches Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and specific packaging options such as tape and reel or cut tape against current datasheet revisions. Ensure the supplier provides valid traceability documentation to mitigate risks associated with obsolete or counterfeit logic ICs.

Latches Selection Notes

Select this component when designing circuits requiring fast octal latching with inverted outputs. Compare propagation delays and drive capabilities against alternative F-series parts if timing margins are tight. Verify that the SOIC-20 package fits the PCB footprint and thermal requirements. Consider power consumption levels relative to system constraints during continuous operation.

Latches Part Context

This part belongs to the widely adopted 74F logic family, known for speed comparable to standard TTL but with improved power efficiency. The 74F533 variant specifically addresses needs for multi-bit storage in high-frequency environments. Fairchild Semiconductor, now part of onsemi, manufactured this component for industrial and commercial electronics before its discontinuation.

Latches Replacement Considerations

Check for equivalents from onsemi or other manufacturers offering compatible F-series octal latches. Verify pin compatibility and electrical specifications match exactly. Note that some substitutes may require package adaptation or voltage level adjustments.
