DESCRIPTION

TheSP3243productsare3driver/5receiverRS-232transceiversolutionsintendedforportableorhand-

held applications such as notebook and palmtop computers. The SP3243 includes one complementary

receiver that remains alert to monitor an external device's Ring Indicate signal while the device is

shutdown. The SP3243E and EB devices feature slew-rate limited outputs for reduced crosstalk and

EMI. The "U" and "H" series are optimized for high speed with data rates up to 1Mbps, easily meeting

the demands of high speed RS-232 applications. The SP3243 series uses an internal high-efficiency,

charge-pumppowersupplythatrequiresonly0.1μFcapacitorsin3.3Voperation. Thischargepumpand

Sipex's driver architectureallowtheSP3243seriestodelivercompliantRS-232performancefrom a single

power supply ranging from +3.0V to +5.5V. 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.
