DESCRIPTION

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.
