SN74ALS540NE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALS540NE4 is an octal buffer and line driver from the Texas Instruments ALS logic family. It features eight non-inverting channels with three-state outputs, housed in a 20-pin DIP package. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical specifications include a propagation delay of 12 ns, a low-level output current capability of 24 mA, and a high-level output current of -15 mA. It supports through-hole mounting and functions reliably across an operating temperature range of 0°C to +70°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'E4' against the manufacturer's latest documentation to confirm lead-free compliance status and RoHS alignment. Confirm that the PDIP-20 package matches the target PCB footprint requirements. Ensure the ordering information corresponds to the exact SN74ALS540NE4 designation to avoid confusion with standard or alternative variants.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring robust octal buffering with bus isolation capabilities. The ALS series offers a balance of speed and power consumption compared to older LS technologies. Verify that the 5V logic levels are compatible with the source and destination devices in the circuit design.
