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.

Active production — no obsolescence risk

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.
