SN74ALS541-1NSR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALS541-1NSR is an octal buffer and line driver from the Texas Instruments ALS logic family, housed in a 20-pin SOIC package. It features non-inverting polarity with three-state outputs. The device operates within a supply voltage range of 4.75 V to 5.25 V. Key electrical parameters include a high-level output current of -15 mA and a low-level output current of 48 mA. Static current is specified at 6 mA, while maximum operating power supply current reaches 25 mA. Propagation delay is 14 ns, and the component supports an operating temperature range from 0°C to +70°C.

Buffers, Drivers, Receivers, Transceivers FAQ

What is the logic polarity of the SN74ALS541-1NSR?

The device features non-inverting polarity, meaning the output signals follow the input states directly.

How does the three-state output benefit bus applications?

The three-state outputs allow multiple devices to share a common data bus by enabling high-impedance states when not actively driving.
