SP3222J

The SP3222J is one member of the intelligent +3.0 V to +5.5 V RS-232 transceiver that uses an internal high-efficiency, charge-pump power supply that requires only 0.1µF capacitors in 3.3V operation. Also this device is a 2-driver/2-receiver device and is a 3-driver/5-receiver device ideal for laptop/notebook computer and PDA applications.

Features of the SP3222J are:(1)Meets true EIA/TIA-232-F Standards from a +3.0V to +5.5V power supply;(2)Interoperable with EIA/TIA-232 and adheres to EIA/TIA-562 down to a +2.7V power source;(3)AUTO ON-LINE® circuitry automatically wakes up from a 1µA shutdown;(4)Minimum 120Kbps data rate under load;(5)Regulated Charge Pump Yields Stable RS-232 Outputs Regardless of VCC Variations;(6)ESD Specifications: +2kV Human Body Model.

The absolute maximum ratings of the SP3222J 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)SHUTDOWN, EN: -0.3 V to +6.0 V;(7)Storage Temperature: -65°C to +150°C;(8)TxOUT: Continuous;(9)TxOUT: +/- 15 V;(10)RxOUT, STATUS: -0.3 V to (Vcc + 0.3 V).
