SN74ALS2541DW

Overview

The SN74ALS2541DW is an octal buffer and line driver from Texas Instruments, belonging to the Advanced Low-power Schottky (ALS) logic family. It features eight non-inverting inputs with three-state outputs housed in a 20-pin SOIC package. The device operates within a supply voltage range of 4.75 V to 5.25 V. Key electrical characteristics include a high-level output current of -15 mA and a low-level output current of 48 mA. Static current consumption is specified at 6 mA, with a maximum operating temperature of +70°C.

Feature Summary

• Provides octal buffering and line driving capabilities for digital signal integrity
• Features three-state outputs to facilitate bus-oriented memory and circuit designs
• Utilizes Advanced Low-power Schottky technology for high-speed operation

Applications

• Bus-oriented memory and circuit architectures
• Clock distribution circuits
• Signal buffering between different logic stages

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as indicated in official documentation. Check for discontinuation notices, as legacy ALS series components may have limited availability. Ensure the SOIC-20 package matches your PCB footprint requirements before ordering.

Selection Notes

Select this component when designing systems requiring octal buffering with three-state control. The ALS series offers a balance of speed and power consumption suitable for general-purpose digital applications. Consider the 48 mA low-level sink capability for driving moderate loads. Verify that the 0°C to +70°C commercial temperature range meets your environmental specifications.

Part Context

This part belongs to the SN74ALS2541 series of octal buffers. It is functionally similar to other octal drivers but distinguished by its specific ALS logic characteristics and non-inverting polarity. The DW suffix indicates the 20-pin Small Outline Integrated Circuit package type used for surface-mount assembly.

Replacement Considerations

Direct substitutes include the SN74ALS2541N (PDIP package) for through-hole applications. Cross-family replacements like the SN74ACT241DW offer similar functionality with CMOS technology but differ in electrical parameters and pinout compatibility should be verified against specific design requirements.
