Product details

30 Mbps quad driver for RS-422/RS-485 buses

The SN75LBC174ADW is a quad RS-422/RS-485 line driver from Texas Instruments, delivering a 30 Mbps data rate over a 4.75 V to 5.25 V supply range. With four drivers and no receivers (4/0 configuration), it is designed for simplex or transmit-only bus nodes where the receiver function is handled elsewhere on the board.

20-SOIC wide-body footprint and commercial temperature range

Housed in a 20-SOIC package with a 7.50 mm body width, the SN75LBC174ADW requires a wide-body SOIC-20 land pattern — not the narrow 3.9 mm variant.

Active production, ROHS3 compliant

Sourced per RFQ against the BOM quantity.

Frequently asked questions

What is the maximum data rate of the SN75LBC174ADW?

The SN75LBC174ADW supports a maximum data rate of 30 Mbps over RS-422 or RS-485 links.

What package does the SN75LBC174ADW come in?

It comes in a 20-SOIC wide-body package (0.295-inch / 7.50 mm width) with surface-mount termination.

Is the SN75LBC174ADW a suitable replacement for the SN75LBC174AN?

The SN75LBC174AN is a DIP-20 through-hole version of the same quad driver. The SN75LBC174ADW is the surface-mount equivalent in a 20-SOIC wide package. Electrical specifications are identical, but the package and mounting method differ — confirm the board footprint and assembly process before substituting.
