描述
The ST4E1250F is a low-power differential line transceiver for data transmission standard RS485 applications in full-duplex mode.
ST4E1250F operates up to 50 Mbps. It is ideal for multi-point applications in a constraint and difficult industrial environment. It is robust to ESD transients. In particular, the bus pins support ±12 kV IEC 61000-4-2 contact discharge. It features robust hot-swap capability while switching on and off, or during plug-in. The fail-safe receiver ensures a logic-high output when the inputs are shorted, open, or terminated bus. The high level of receiver hysteresis improves the noise rejection and the signal integrity.
The ST4E1250F is available in a small 3 x 3 mm DFN10 package and operates over a -40 °C to 125 °C temperature range.
