1 / 25 page 1 Date: 6/2/04 SP3223EB/3243EB +3.0V to +5.5V RS-232 Transceivers © Copyright 2004 Sipex Corporation SP3223EB/3243EB Intelligent +3.0V to +5.5V RS-232 Transceivers The SP3223EB and SP3243EB products are RS-232 transceiver solutions intended for portable or hand-held applications such as notebook and palmtop computers. The SP3223EB and SP3243EB use an internal high-efficiency, charge-pump power supply that requires only 0.1µF capacitors in 3.3V operation. This charge pump and Sipex's driver architecture allow the SP3223EB/3243EB series to deliver compliant RS-232 performance from a single power supply ranging from +3.0V to +5.5V. The SP3223EB is a 2-driver/2-receiver device, and the SP3243EB is a 3-driver/5-receiver device ideal for laptop/notebook computer and PDA applications. The SP3243EB includes one complementary receiver that remains alert to monitor an external device's Ring Indicate signal while the device is shutdown. The AUTO ON-LINE® feature allows the device to automatically "wake-up" during a shutdown state when an RS-232 cable is connected and a connected peripheral is turned on. Otherwise, the device automatically shuts itself down drawing less than 1µA. ■ Meets true EIA/TIA-232-F Standards from a +3.0V to +5.5V power supply ■ Interoperable with EIA/TIA-232 and adheres to EIA/TIA-562 down to a +2.7V power source ■ AUTO ON-LINE® circuitry automatically wakes up from a 1µA shutdown ■ Minimum 250kbps data rate under load ■ Regulated Charge Pump Yields Stable RS-232 Outputs Regardless of V CC Variations ■ Enhanced ESD Specifications: +15kV Human Body Model +15kV IEC1000-4-2 Air Discharge +8kV IEC1000-4-2 Contact Discharge DESCRIPTION SELECTION TABLE Applicable U.S. Patents - 5,306,954; and other patents pending. e c i v e Ds e il p p u S r e w o P2 3 2 - S R s r e v i r D 2 3 2 - S R s r e v i e c e R l a n r e t x E s t n e n o p m o C E N I L - N O O T U A ® y r t i u c r i C e t a t S - 3 L T Tf o . o N s n i P B E 3 2 2 3 P SV 5 . 5 + o t V 0 . 3 +2 2 s r o t i c a p a c 4S E YS E Y0 2 B E 3 4 2 3 P SV 5 . 5 + o t V 0 . 3 +3 5 s r o t i c a p a c 4S E YS E Y8 2 ® V- 1 2 3 4 17 18 19 20 5 6 7 16 15 14 SHUTDOWN C1+ V+ C1- C2+ C2- ONLINE EN R1IN GND VCC T1OUT STATUS 8 9 10 11 12 13 R2IN R2OUT SP3223EB T2OUT T1IN T2IN R1OUT Now Available in Lead Free Packaging |
