MAX3250 Datasheet (Maxim) - 50V Isolated / 3.0V to 5.5V / 250kbps / 2 Tx/2 Rx / RS-232 Transceiver

MAX3250, 50V Isolated / 3.0V to 5.5V / 250kbps / 2 Tx/2 Rx / RS-232 Transceiver

The MAX3250 is a 3.0V to 5.5V powered, ±50V isolated EIA/TIA-232 and V.28/V.24 communications interface with high data-rate capabilities.

The MAX3250 is a dual die part that operates with up to ±50V difference between the RS-232 side and the logic side (ISOCOM to GND).

This makes the device ideal fo

MAX3250 Features

* a FAULT open-drain output to signal an excessive isolated-side voltage condition on any of the RS232 inputs. This output can drive an alarm LED or can be monitored by the processor to prevent operation under these conditions. The receiver outputs are high impedance in shutdown, allowing multiple int
