Product details

40 Mbps half-duplex transceiver for industrial buses

With 35 mV of receiver hysteresis, it rejects noise on long cable runs common in factory automation, building management, and motor-drive networks.

If your system runs on 3.3 V, you need a level translator or a different transceiver. The 8-DIP through-hole package is a deliberate choice: it survives higher vibration than an SOIC footprint and fits socketed prototyping boards, but it consumes more board area than an SO-8. For production runs where pick-and-place speed matters, consider the SOIC-8 variant (SN65HVD05D) — same silicon, same performance, smaller footprint.

TI lists the SN65HVD05P as Active. For dual-sourcing resilience, the SN65HVD05 family shares the same pinout across data-rate options (SN65HVD03, SN65HVD07, etc.), so a speed-grade swap is a direct drop-in without board rework.

Frequently asked questions

What is the data rate of SN65HVD05P?

The SN65HVD05P supports a data rate of 40 Mbps. That is the maximum signaling rate on the bus; actual throughput depends on cable length, termination, and the number of nodes.

Is SN65HVD05P half-duplex or full-duplex?

It is half-duplex. The single driver and receiver share the same bus pair, so the transceiver must be direction-controlled — typically via a GPIO or UART DE/RE signal. For full-duplex operation, look at the SN65HVD11 or SN65HVD12 family.

Is SN65HVD05P RoHS compliant?

The SN65HVD05P is listed as RoHS compliant per TI's standard lead-free plating. No separate RoHS certificate is needed for most procurement systems — the part ships with the standard green/RoHS marking.

What is the equivalent of SN65HVD05P?

Within the same family, the SN65HVD05D is the SOIC-8 surface-mount equivalent with identical electrical specs. For a pin-compatible speed-grade alternative, the SN65HVD07P offers 50 Mbps in the same DIP footprint. Both are active and sourced through the same channels.
