DESCRIPTION

The SP3238EE device is an RS-232 transceiver solution intended for portable or hand-held

applications such as notebook and palmtop computers. The SP3238EE uses an internal

high-efficiency, charge-pump power supply that requires only 0.1碌F capacitors in 3.3V

operation. This charge pump and Sipex's driver architecture allow the SP3238EE device to

deliver compliant RS-232 performance from a single power supply ranging from +3.0V to

+5.0V. The SP3238E is a 5-driver/3-receiver device, ideal for laptop/notebook computer and

PDA applications. The SP3238EE 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

廬

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 1碌A(chǔ).

Applicable U.S. Patents - 5,306,954; and other patents pending.
