Product details

8-bit buffer for 5V bus isolation

The SN74ALS541NS: It provides a single-element, 8-bit wide buffer that isolates or drives a 5V bus with 15mA source and 24mA sink capability. The surface-mount package suits dense PCB layouts.

Supply rail and drive limits

The 3-state outputs allow multiple buffers to share a common bus without contention; the output-enable control tristates all eight channels. Output current is rated 15mA high and 24mA low.

It belongs in office equipment, appliances, indoor telecom racks, or test gear — not in a motor drive, engine bay, or outdoor enclosure where the ambient can dip below freezing or climb above 70°C.

Frequently asked questions

What are the alternatives to SN74ALS541NS?

For a through-hole alternative, the SN74LS645-1N is a non-inverting transceiver with similar supply voltage and temperature range, but in a DIP package.
