Product details

50 Mbps RS-485 transceiver for industrial buses

Receiver hysteresis is specified at 30 mV, which helps keep the bus from chattering on long twisted-pair runs in electrically noisy environments.

New designs can commit to it without near-term obsolescence risk.

That means a PCB already laid out for a generic SOIC-8 RS-485 part can take this device with zero board respin. Surface-mount only — no through-hole variant in this order code.

Sourcing and procurement note

The active lifecycle status removes the urgency of a last-time-buy, but the usual diligence on date-code consistency and lot traceability applies when procuring from the open market.

Frequently asked questions

Is THVD1450D RoHS compliant?

The THVD1450D is listed as RoHS compliant in the standard TI product marking. No separate RoHS certificate is needed for typical procurement — the manufacturer's packing slip and label carry the compliance statement.

Can THVD1450D be used as a substitute for SN65HVD1450D?

The THVD1450D and SN65HVD1450D share the same base function — a 50 Mbps half-duplex RS-485 transceiver in an 8-SOIC package — and are generally considered pin-compatible drop-in replacements.

What is the lead time for THVD1450D when ordering?

Because this is an active, standard-product transceiver, lead times typically fall within the normal range for TI interface ICs, but exact weeks depend on current factory backlog and distributor inventory.
