1 / 23 page 1 Rev P 11/20/06 SP3224E-SP3227E Transceivers with Auto On-line® Plus © 2006 Sipex Corporation SP3224E-SP3227E FEATURES ■ 15kV ESD protected RS-232 I/O pins ■ Auto On-line® Plus automatic power saving mode ■ Meets true EIA/TIA-232-F standards from +3.0V to +5.5V power supply. ■ Adheres to EIA/TIA-562 for interoperability with EIA/TIA-232 down to a +2.7V supply voltage ■ Regulated charge pump yields stable RS-232 outputs ■ Drop-in replacement to MAX3224, ICL3224, MAX3225, ICL3225, MAX3226, ICL3226, MAX3227 and ICL3227 ■ SP3224E and SP3225E reduced EMI with a slew rate controlled 250kbps data rate ■ SP3226E and SP3227E- high speed data rate of 1 Mbps. ■ Available in RoHS compliant, Lead Free Packaging 3.0V to 5.5V RS-232 Transceivers with Auto On-Line® Plus DESCRIPTION TYPICAL APPLICATIONS ■ Diagnostic/Serial ports on embedded applications ■ Handheld Test Equipment ■ PC related Peripherals and Equipment ■ Battery Powered Equipment ■ Point-of-sale Equipment ■ Set-top Box The SP3224E/3225E are 2-driver/2-receiver devices and the SP3226E/SP3227E are 1- driver/1-receiver devices. All are ideal for computer peripherals, point-of-sale equipment, consumer and embedded applications. These devices 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 it to deliver compliant RS-232 perfor- mance from a single power supply ranging from +3.0V to +5.5V. At voltages between 2.7V and 3.0V the driver outputs are compliant with RS-562 and can interface to RS-232 over short cables. The Auto On-line® Plus feature allows the device to automatically “wake-up” during a shut- down state upon detecting activity and to enter a low power shutdown if idle. This power saving feature functions without system intervention or modifications to software or driv- ers. SELECTION TABLE All devices feature 3.0V to 5.5V power supply, 4 small charge pump capacitors, and 15kV ESD protection.
