SP3220U

The SP3220U is one member of the SP3220 family which is designed as the high speed +3.0V to +5.5V RS-232 driver/receiver pair device that has a high-efficiency, charge-pump power supply that requires only 0.1µF capacitors in 3.3V operation. Also this device has a low-power shutdown mode where the driver outputs and charge pumps are disabled. During shutdown, the supply current falls to less than 1µA.

Features of the SP3220U are:(1)Meets True RS-232 Protocol Operation From A +3.0V to +5.5V Power Supply;(2)Minimum 250 Kbps Data Rate (SP3220B) or 1Mbps Data Rate (SP3220U) under Fully Load;(3)1µA Low-Power Shutdown With Receivers Active;(4)Interoperable With EIA/TIA - 232 and adheres to EIA/TIA - 562 Down to +2.7V Power Source;(5)Pin-Compatible With The MAX3221E Device Without The AUTO ON-LINE® Feature;(6)ESD Specifications: +2kV Human Body Model.

The absolute maximum ratings of the SP3220U can be summarized as:(1)Vcc: -0.3 V to +6.0 V;(2)V+: -0.3 V to +7.0 V;(3)V-: -0.3 V to +7.0 V;(4)V+ + |V-|: +13 V;(5)ICC (DC VCC or GND current): +/- 100 mA;(6)Storage Temperature: -65°C to +150°C;(7)TxOUT: Continuous;(8)RxOUT: -0.3V to (VCC+0.3V);(9)TxOUT: +/- 13.2 V.
