DM74ALS580AN

Latches Overview

The DM74ALS580AN is an octal D-type transparent latch manufactured by Fairchild Semiconductor, part of the 74ALS logic family. It features a single channel with eight independent latches and three-state outputs. The device operates within a supply voltage range of 4.5V to 5.5V and supports a propagation delay of 3ns. It is housed in a 20-pin PDIP package with a standard 0.300-inch width. The component is designed for through-hole mounting and functions within an operating temperature range of 0°C to 70°C.

Latches Feature Summary

• Octal configuration providing eight independent D-type transparent latch circuits within a single integrated circuit.
• Three-state output capability allowing effective bus isolation when drivers are disabled.
• Advanced Low-power Schottky (ALS) technology ensuring improved switching speed and reduced power consumption compared to standard TTL counterparts.

Latches Applications

• Memory systems requiring data storage and buffering
• Microprocessor interface circuits for temporary data holding
• Asynchronous bidirectional data buses

Latches Procurement Notes

Verify component authenticity as this specific Fairchild part number is discontinued. Confirm that any available stock represents original manufacturer inventory rather than refurbished units. Ensure the replacement SN74ALS580BN from Texas Instruments matches the required pinout and electrical specifications for your specific application design before finalizing procurement decisions.

Latches Selection Notes

Select this component for designs requiring high-speed data latching with low power dissipation. The ALS series offers superior performance over standard 74LS devices while maintaining compatibility. Consider the availability of direct substitutes like the SN74ALS580BN if new production units are unavailable. Evaluate the 20-PDIP package constraints against your PCB layout requirements.

Latches Part Context

This device belongs to the widely adopted 74-series logic family, specifically the Advanced Low-power Schottky (ALS) subset. The ALS family was engineered to provide faster switching speeds and lower power usage than previous generations. The DM74ALS580AN serves as a foundational building block for digital logic systems requiring parallel data retention and controlled output states.

Latches Replacement Considerations

The SN74ALS580BN from Texas Instruments is documented as a direct substitute for the DM74ALS580AN.
