SN74ALS2541DWR

Overview

The SN74ALS2541DWR is an octal line driver and MOS driver featuring three-state outputs, manufactured by Texas Instruments. It belongs to the ALS logic series and is housed in a 20-pin SOIC package. The device operates with a supply voltage range of 4.75 V to 5.25 V. It provides non-inverting buffering for eight input lines. The component supports a maximum operating temperature of +70°C and a minimum of 0°C. Static current consumption is specified at 9 mA. High-level output current is rated at -15 mA, while low-level output current reaches 48 mA.

Feature Summary

• Provides octal buffering with true (non-inverting) output polarity
• Features three-state outputs for bus-oriented applications
• Compatible with standard TTL input levels

Applications

• Bus-oriented memory and address drivers
• Clock drivers and buffer circuits
• MOS memory address and data drivers

Procurement Notes

Verify the specific suffix 'DWR' corresponds to the tape and reel packaging format when ordering. Confirm that the ALS logic family requirements align with system design constraints. Ensure the SOIC-20 footprint matches the PCB layout specifications. Check for any recent product change notices regarding pinout or electrical characteristics updates from the manufacturer.

Selection Notes

Select this component for designs requiring high-speed octal buffering with three-state control. The ALS series offers improved speed-power product compared to standard LS logic. Consider the 48 mA low-level sink capability for driving heavy loads. Verify compatibility with the system's 5 V power supply tolerance and thermal management capabilities within the industrial temperature range.

Part Context

This part is part of the SN74ALS2541 family of octal buffers and line drivers. It serves as a digital logic interface component for transferring data between buses and peripheral devices. The device is designed for high-density systems requiring multiple buffered channels. It complements other ALS series components like latches and flip-flops in complex digital architectures.

Replacement Considerations

Check for direct equivalents such as the SN74ALS2541DW variant if reel packaging is not required. Verify functional compatibility with other octal three-state drivers in the ALS family. Ensure substitute parts maintain the same pinout and electrical specifications for seamless integration.
