... DESCRIPTION The SP3203 provides a RS-232 transceiver solution for portable and hand-held applications such as palmtops, PDA's and cell phones. The SP3203 uses an internal high-efficiency, charge-pump that requires only 0.1µF capacitors during 3.3V operation. This charge pump and Sipex's driver architecture allow the SP3203 to deliver compliant RS-232 performance from a single power supply ranging from +3 ...

... The receivers convert ±5.0V EIA/TIA-232 levels to TTL or CMOS logic output levels. Receivers are disabled when in shutdown. The truth table logic of the SP3203 driver and re- ceiver outputs can be found in Table 1. Since receiver input is usually from a transmis- sion line where long cable lengths and system interference can degrade the signal, the inputs have a typical hysteresis margin of 500mV ...

... Table 1. SHUTDOWN Truth Table. (Note: When device in shutdown, the SP3203's charge pump is turned off and V+ decays pulled to ground and the transmitter outputs CC. are disabled as High Impendance). consists of a regulated dual charge pump that provides output voltages of 5.5V regardless of the input voltage (V ) over the +3 ...

... V Supply Level L Current RS-232 serial tranceivers are designed with fixed 5V or 3.3V TTL input/output voltages levels. The V function in the SP3203 allows the L end user to set the TTL input/output voltage levels independent connecting V CC the main logic bus of system, the TTL input/ output limits and threshold are reset to interface with the on board low voltage logic circuity ...

... ESD TOLERANCE The SP3203 incorporates ruggedized ESD cells on all driver output and receiver input pins. The Human Body Model has been the generally accepted ESD testing method for semiconductors. This method is also specified in MIL-STD-883, Method 3015.7 for ESD testing. The premise of this ESD test is to simulate the human body’ ...
