sp3232een is a level conversion chip. Level conversion chip is in the system circuit of different voltage levels, the communication between the two also meets the signal level match, if not matched, it must be level conversion, level conversion chip is for this existence. This starts with the signal level of different communication protocols, usually in electronic circuits, the circuit system below 24V is encountered.
SP3232EEN is an RS-232 level conversion chip.
Chip characteristics:
1, 3.0V-5.5V power supply;
2, 120kbps transmission rate;
3, 15kv air discharge;
4, 8kv contact discharge.
