Product details

Quad differential line receiver for RS-422/423/485 buses

The SN75175D is a quad differential line receiver from Texas Instruments designed for balanced transmission lines using RS-422, RS-423, or RS-485 protocols. It integrates four independent receivers in a single 16-SOIC package, each with 50 mV of hysteresis to reject noise on long cable runs. Supply voltage is 4.75V to 5.25V, a narrow 5V ±5% rail that demands a regulated supply — not suitable for unregulated 5V buses that sag below 4.75V under load.

The part is ROHS3 compliant. For volume BOM commitments, the part is sourced through standard TI distribution channels.

16-SOIC narrow-body — layout checklist

Package is 16-SOIC with a 0.154-inch (3.90 mm) body width, the narrow-body variant. The supplier device package is 16-SOIC. Footprint matches industry-standard SOIC-16 narrow land pattern. Mounting is surface-mount only.

Frequently asked questions

How many receivers does SN75175D have?

Four independent receivers in a single package. The driver count is zero — this is a receiver-only device.

Is SN75175D equivalent to any other TI receiver?

The SN75175 is the base family. The SN75175D is the 16-SOIC variant. Pin-compatible alternatives within the TI portfolio include the SN75ALS176 and SN75LBC176, but those are transceivers (driver + receiver), not receiver-only. Confirm the BOM function before substituting.
