74F843SCX

Latches Overview

The Fairchild Semiconductor 74F843SCX is a high-speed, low-power 9-bit transparent latch featuring TTL-compatible inputs and tri-state outputs. It operates within a voltage range of 4.5V to 5.5V and supports data rates up to 100MHz. The device utilizes a 24-pin SOIC package with a 0.3-inch width. Key electrical characteristics include a propagation delay of 10ns and output drive capabilities of 24mA source/sink current.

Latches Feature Summary

• Transparent latch architecture for direct data path control
• Tri-state outputs enable efficient bus-oriented system designs
• TTL-compatible input logic levels simplify interface integration

Latches Applications

• High-speed data buffering in digital systems
• Bus-oriented memory address latching
• Parallel data storage in communication interfaces

Latches Procurement Notes

Verify the specific suffix 'SCX' against the manufacturer's official ordering guide to confirm the exact package variant and lead-free status. Ensure compatibility with existing PCB footprints for the 24-pin SOIC-24 wide configuration. Cross-reference RoHS compliance documentation for regulatory adherence in final assembly processes.

Latches Selection Notes

Select this component when a 9-bit transparent latch with tri-state capability is required. Compare propagation delays and power consumption against similar AC or ACT series alternatives if lower voltage operation is needed. Verify that the TTL-compatible input thresholds meet the driving circuit requirements for reliable signal integrity.

Latches Part Context

This part belongs to the 74F series of high-speed CMOS logic devices. It serves as a functional equivalent to other 9-bit latches in the industry standard logic family. The device provides a balance between speed and power dissipation suitable for general-purpose digital applications requiring parallel data storage.

Latches Replacement Considerations

Check for pin-compatible substitutes such as the 74F843SPC or 74F843SPCX from the same manufacturer. Verify that alternative sources maintain identical electrical specifications and package dimensions to ensure seamless integration without redesigning the host board.
