SP3243ECA

The SP3243ECA is designed as one kind of RS-232 transceiver solutions intended for portable or hand-held applications such as notebook and palmtop computers. It uses 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 performance from a single power supply ranging from +3.3V to +5.0V.

SP3243ECA has six features. (1)Meets true EIA/TIA-232-F standards from a +3.0V to +5.5V power supply. (2)Interoperable with EIA/TIA-232 and adheres to EIA/TIA-562 down to a +2.7V power source. (3)AUTO ON-LINE circuitry automatically wakes up from a 1µA shutdown. (4)Minimum 120Kbps data rate under load. (5)Regulated charge pump yields stable RS-232 outputs regardless of Vcc variations. (6)Enhanced ESD specifications: +15KV human body model, +15KV IEC1000-4-2 air discharge, +8KV IEC1000-4-2 contact discharge. Those are all the main features.

Some SP3243ECA absolute maximum ratings have been concluded into several points as follow. (1)Its Vcc would be from -0.3V to 6.0V. (2)Its V+ would be from -0.3V to +7.0V. (3)Its V- would be from +0.3V to -7.0V. (4)Its V+ +|V-| would be 13V. (5)Its Icc (DC Vcc or GND current) would be +/-100mA. (6)Its input voltage would be from -0.3V to +6.0V. (7)Its output voltage would be from -0.3V to Vcc+0.3V. (8)Its storage temperature range would be from -65°C to 150°C. (9)Its power dissipation per package would be 900mW. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some SP3243ECA electrical characteristics are concluded as follow. (1)Its supply current auto on-line would be typ 1ua and max 10uA. (2)Its supply current shutdown would be typ 1uA and max 10uA. (3)Its supply current auto on-line disabled would be typ 0.3mA and max 1.0mA. And so on.
