MAXIM INTEGRATED / ANALOG DEVICES MAX251EPD RS-232 Isolator
The MAX251EPD+ is a 5V-powered, isolated RS232 driver and receiver integrated in a 14-pin DIP package. It forms the core of a fully isolated RS232 dual transmitter and receiver setup. By combining multiple functions on two chips, it greatly reduces the cost and complexity of isolated digital interfaces. The system requires only four low-cost optocouplers, four capacitors, a diode, and a small pot-core transformer to create a 19.2k baud transceiver. Higher data rates can be achieved using high-speed optocouplers. The device includes circuitry for driving and receiving data from optocouplers and incorporates a push-pull transformer driver to supply power to the isolated side. It is suitable for use in bridging ground differentials and data links to analog circuits. Key features include a supply voltage range of 4.5V to 5.5V, operational temperature from -40°C to 85°C, isolated data interface, positive supply current of 2.5mA, very low shutdown power of 5µW, and bidirectional data communication with 2 transmitters and 2 receivers. The enable and disable times for the 3-state control are 3.5µs and 1µs, respectively, with a maximum threshold voltage of 2V.
