The MAX202 transceiver is designed for RS232 & V.28 communication interfaces where a plusmn 12V supply is not available. On-board charge pumps convert the 5V input to the plusmn 10V needed for RS232 output levels. The drivers & receivers meet all EIATIA-232E & CCITTV.28 specifications at a data rate of 20kbitssec. The device requires just four external capacitors to provide the voltage conversion. Supplied in a 16-pin DIL package MAX202CPE.
