The integrated charge pump generates \u00b110V RS-232 levels, requiring only four external 1\u00b5F capacitors. The 16-pin DIP (PDIP) package provides 2 drivers and 2 receivers for full-duplex communication at up to 120 kbps.","working_principle":"The MAX232 uses an internal charge pump (voltage doubler and inverter) to generate \u00b110V supplies from the 5V VCC. The drivers convert TTL\/CMOS logic levels to RS-232 voltage swings (\u00b15V to \u00b110V). The receivers convert RS-232 levels back to TTL\/CMOS. The charge pump requires four external 1\u00b5F capacitors.","pin_description":"
