74F573PC

Latches Overview

The Fairchild Semiconductor 74F573PC is an octal D-type transparent latch integrated circuit housed in a 20-pin PDIP package. It features tri-state outputs and operates within a supply voltage range of 4.5V to 5.5V. The device contains eight independent D-type latches, providing a single channel configuration with eight input lines and eight output lines. This component is part of the 74F logic series, designed for high-speed digital applications requiring data storage and bus interfacing capabilities.

Latches Feature Summary

• Octal D-type transparent latch architecture with eight independent channels
• Tri-state output capability for efficient bus management
• Compatible with standard 5V logic supply voltages

Latches Applications

• Data storage in digital systems
• Bus driver interfaces
• Parallel-to-serial conversion circuits

Latches Procurement Notes

Verify the obsolete status of this component before procurement planning. Confirm that the 20-PDIP package matches your PCB footprint requirements. Ensure compatibility with existing 74F series logic levels in your design. Check for RoHS compliance documentation if required by your manufacturing standards. Consider lead times due to potential discontinuation.

Latches Selection Notes

Select this component when an octal latch with tri-state outputs is required in a through-hole package. It is suitable for designs utilizing the 74F logic family for speed performance. Verify that the 4.5V to 5.5V operating range aligns with your system power supply. Ensure the 20-pin DIP form factor fits your assembly constraints.

Latches Part Context

This part belongs to the Fairchild Semiconductor 74F logic family, known for high-speed operation. The 74F573 specifically provides octal latching functionality. It is distinct from similar parts like the 74F574 (flip-flop) or 74F373 (latch with different pinout). The 'PC' suffix indicates the plastic dual in-line package type.

Latches Replacement Considerations

Check for direct replacements such as the ON Semiconductor variant 74F573PC. Other compatible octal latches in the 74F series may serve as alternatives if pinouts match. Verify functional equivalence before substitution.
