Enhanced protection and reliability
Integrated fail‑safe receiver, hot‑swap capability and up to ±16 kV IEC 61000‑4‑2 contact ESD protection maximize system robustness and uptime
Robust high-speed RS-485 communication
Up to 50 Mbps, full‑duplex operation and high receiver hysteresis ensure reliable data integrity in noisy industrial networks
Description
The ST4E1650F is a low-power differential line transceiver for data transmission standard RS485 applications in full-duplex mode.
The ST4E1650F operates up to 50 Mbps. It is ideal for multi-point applications in a constrained and difficult industrial environment. It is robust to ESD transients. In particular, the bus pins support ±16 kV IEC 61000-4-2 contact discharge. It features robust hot-swap capability during switching on and off, or during plug-in. The fail-safe receiver ensures a logic-high output when the inputs are shorted, open, or indeterminate. The high level of receiver hysteresis improves the noise rejection and the signal integrity.
The ST4E1650F is available in a small 3 mm x 3 mm DFN10 package and operates in a -40 °C to 125 °C temperature range.
