MAXIM INTEGRATED / ANALOG DEVICES MAX250EPD Isolated RS-232 Interface Module

The MAX250EPD+ is a +5V powered, isolated RS232 driver and receiver in a 14-pin DIP package. It forms the core of a complete electronically isolated RS232 dual transmitter and receiver system. By integrating multiple functions onto two chips, it reduces the cost and complexity of isolated digital interfaces. The device supports data rates up to 19.2k baud with four low-cost optocouplers, four capacitors, a diode, and a small pot-core transformer. Higher data rates are achievable using high-speed optocouplers. The set includes circuitry for driving and receiving optocouplers and features a push-pull transformer driver that supplies power to the isolated side of the interface. It is used for bridging ground differentials and data links in analog circuits. Specifications include a supply voltage range of 4.5V to 5.5V, operational temperature from -40°C to 85°C, and a maximum supply current of 0.5mA during operation. The device contains two transmitters and two receivers, with a switching frequency of 275kHz at 25°C, and a maximum driver on-resistance of 50 ohms at 25mA. Its low shutdown power consumption is 5µW, with a shutdown current of 100µA at 55°C to 125°C.
