DM74ALS576AWM

Overview

The DM74ALS576AWM is an octal D-type edge-triggered flip-flop manufactured by Fairchild Semiconductor. It features 3-state outputs and operates within a voltage range of 4.5V to 5.5V. The device is housed in a 20-lead Small Outline Integrated Circuit (SOIC) package, specifically the MS-013 standard with a 0.300-inch width. It belongs to the Advanced Low-power Schottky (ALS) logic series, designed for high-speed digital applications requiring low power consumption.

Feature Summary

• Octal configuration providing eight independent D-type edge-triggered flip-flops
• Three-state output capability allowing effective bus isolation when disabled
• Advanced Low-power Schottky technology ensuring improved speed and reduced power dissipation

Applications

• Register storage in microprocessor systems
• Shift register configurations for data serialization
• Buffering in asynchronous bidirectional data buses

Procurement Notes

Verify the manufacturer source carefully, as this component is produced by multiple entities including Fairchild, ON Semiconductor, Texas Instruments, and Rochester Electronics. Confirm that the specific ordering suffix matches your required package and temperature grade specifications. Ensure the datasheet revision aligns with your design requirements before finalizing procurement decisions.

Selection Notes

Select this component when designing systems requiring octal storage elements with tri-state output control. It serves as a suitable replacement for standard 74LS576 circuits where lower power consumption and faster switching speeds are necessary. Consider the 20-pin SOIC package constraints during PCB layout planning to ensure adequate spacing and thermal management.

Part Context

This part belongs to the 74ALS logic family, which bridges the performance gap between standard TTL and low-power Schottky families. The DM74ALS576A variant specifically provides edge-triggered functionality with three-state outputs, making it distinct from non-inverting or transparent latch variants within the same series.

Replacement Considerations

• DM74ALS576AN
• SN74ALS576N
