DM74ALS580AWMX

Latches Overview

The DM74ALS580AWMX is an octal D-type transparent latch manufactured by Fairchild Semiconductor in a 20-SOIC package. It features totem-pole 3-STATE outputs designed for driving highly-capacitive or low-impedance loads. The device operates within a 4.5V to 5.5V supply voltage range and belongs to the Advanced Low-power Schottky (ALS) logic family.

Latches Feature Summary

• Octal D-type transparent latch configuration with single-channel operation
• Totem-pole 3-STATE outputs engineered for high capacitive or low-impedance load driving
• Advanced Low-power Schottky technology ensuring reduced power consumption

Latches Applications

• High-capacitance bus line driving
• Low-impedance load interfacing
• Octal data storage in microprocessor systems

Latches Procurement Notes

Verify the manufacturer designation, as Fairchild Semiconductor's logic division is now part of onsemi. Confirm the specific suffix 'AWMX' corresponds to the SOIC-20 package and RoHS compliance status. Ensure the component matches the original Fairchild datasheet specifications rather than generic equivalents.

Latches Selection Notes

Select this component when an octal latch with 3-STATE output capability is required for driving heavy loads. The ALS series offers a balance of speed and power efficiency suitable for memory and I/O interfaces. Verify that the 20-SOIC footprint fits the target PCB layout constraints.

Latches Part Context

This part is an octal latch from the Fairchild ALS logic family. It differs from the DM74ALS245, which is a bidirectional bus transceiver. The DM74ALS580 focuses on data latching with tri-state outputs, making it distinct from drivers or transceivers in terms of internal logic function and signal flow directionality.

Latches Replacement Considerations

Check for direct substitutes such as the DM74ALS580N or other manufacturers' equivalent octal latches in the 74ALS series. Ensure pin compatibility and electrical characteristics match the original design requirements before substitution.
