SN74ALS541-1DW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALS541-1DW is an octal buffer and line driver from the Texas Instruments ALS logic family. It features eight non-inverting outputs with three-state capability, 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, while operating power supply current reaches 25 mA. The component supports surface mount installation and functions reliably within an ambient temperature range of 0°C to +70°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix '-1' against the manufacturer datasheet to confirm pinout or functional variations compared to standard variants. Ensure the SOIC-20 package dimensions match the target PCB footprint. Confirm RoHS compliance status for the specific manufacturing lot before integration into regulated assemblies.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring high-speed buffering with significant load-driving capabilities. The ALS series offers a balance between speed and power consumption. Verify that the system voltage remains strictly within the 4.75 V to 5.25 V window to ensure proper logic levels and avoid damage to the internal circuitry.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74ALS54x series of octal buffers and line drivers. It shares architectural similarities with the SN74ALS540 but differs in signal polarity. The device is designed for high-performance digital applications where signal integrity and bus isolation are critical requirements for system operation.
