Product details

16-SOIC RS422/RS423 line transceiver

The DS8925MX is a 16-SOIC RS422/RS423 line transceiver with 2 drivers and 3 receivers on a single chip. It operates from a 4.75V to 5.25V supply, making it a direct fit for legacy 5V backplane and cable-extension designs in industrial control and data-acquisition systems.

Driver/receiver count and supply rail

The 2/3 driver/receiver count means one transceiver handles a full-duplex RS422 link plus one additional receiver for a secondary monitor channel. The 4.75V-5.25V supply range is tight — the board's 5V rail must stay within ±5% to keep the part in spec; a 5V rail that dips to 4.5V under load is outside the guaranteed operating window.

Active lifecycle and sourcing

It is not RoHS compliant, so it is suited for repair and legacy production runs that require tin-lead solder processes.

Frequently asked questions

Is DS8925MX compatible with 5V logic?

Yes. The supply voltage range is 4.75V to 5.25V, which is standard 5V logic. The RS422/RS423 protocol levels are 5V-compatible at the bus interface.
