The SP3232ECY-L\/TR from MaxLinear (formerly Sipex\/Exar) is a true +3.0V to +5.5V RS-232 transceiver that complies with EIA\/TIA-232-F standards. It features 2 drivers and 2 receivers with an integrated high-efficiency charge pump that requires only four 0.1uF external capacitors. The device delivers robust ESD protection of plus\/minus 15kV (HBM) and plus\/minus 8kV (IEC 61000-4-2 contact discharge), making it highly reliable for industrial and commercial communication interfaces.<\/p>\n

The device integrates a high-efficiency charge pump power supply that requires only 0.1uF capacitors in 3.3V operation, reducing board space and component count. The 2-driver\/2-receiver configuration supports full RS-232 serial communication with data rates up to 120 kbps. Enhanced ESD protection exceeding +\/-15kV (HBM) ensures robust operation in electrically harsh environments. The TSSOP-16 package provides a compact footprint suitable for space-constrained designs.","working_principle":"The SP3232ECY-L\/TR operates by converting TTL\/CMOS logic levels to RS-232 compliant voltage levels using an integrated dual charge pump. The first charge pump is a voltage doubler that generates approximately +5.5V from the VCC supply, while the second charge pump is a voltage inverter that generates approximately -5.5V. These boosted voltages power the RS-232 driver outputs, ensuring compliance with EIA\/TIA-232-F amplitude requirements even at 3.0V supply. The receivers perform the opposite function, converting RS-232 input levels to TTL\/CMOS output levels with approximately 300mV of hysteresis for noise immunity. A 5kOhm pulldown resistor on each receiver input ensures a defined logic high output when the input is floating.","pin_description":"
