74F533SJ

Latches Overview

The Fairchild Semiconductor 74F533SJ is an octal transparent latch belonging to the F/FAST series. It features eight D-type latches with inverted outputs and three-state capability. The device operates on a single supply voltage ranging from 4.5V to 5.5V. It utilizes a 20-pin Small Outline Package (SOP) for surface mount applications. The component supports synchronous data entry triggered by positive edges and includes an active-low output enable input.

Latches Feature Summary

• Provides eight independent transparent latches with inverted outputs
• Features three-state outputs controlled by an active-low enable signal
• Supports high-speed operation within the F/FAST logic family
• Designed for surface mount integration via standard SOP packaging

Latches Applications

• Data bus buffering in digital systems
• Temporary storage of parallel data in microprocessor interfaces
• Output isolation for bidirectional communication lines

Latches Procurement Notes

Verify the specific manufacturer suffix against current onsemi or Fairchild Semiconductor documentation to confirm pinout compatibility and electrical characteristics. Ensure the procurement source provides valid RoHS compliance certificates as required for modern electronic assembly processes. Cross-reference the package marking codes to distinguish between original manufacturing runs and potential re-marked units.

Latches Selection Notes

Select this component when an octal latch with inverted outputs and tri-state control is required. Compare propagation delay specifications against system timing requirements to ensure signal integrity. Verify that the operating temperature range meets the environmental conditions of the target application. Confirm power supply stability within the specified voltage limits to prevent erratic latch behavior.

Latches Part Context

This part belongs to the 74F series of high-speed CMOS logic devices. It serves as a functional equivalent to other octal latches but distinguishes itself through inverted output polarity. The F/FAST series is characterized by faster switching speeds compared to standard 74LS counterparts, making it suitable for higher frequency digital circuits requiring rapid data handling capabilities.

Latches Replacement Considerations

The 74F373 is functionally similar but lacks output inversion. Verify if non-inverted outputs are acceptable for the design. Check for compatible packages such as SOIC-20 from other manufacturers like Texas Instruments or NXP, ensuring voltage and speed parameters align.
