DESCRIPTIONThe ST3243E device consists of3 drivers,5
receivers anda dual charge-pump circuit. The
device meets the requirementsof EIA/TIA and
V.28/V.24 comunication standards providing high
data rate capability and enhanced electrostatic
discharge (ESD) protection.All transmitter outputs
and receiver input are protectedto ±8KV USING
IEC 1000-4-2 contact discharge and ±15KV using
the Human Body Model. The receiver R2is
always activeto implementa wake-up feature for
serial port.
The ST3243E hasa proprietary low-dropout
transmitter output stage enabling true RS-232
performance froma 3.0Vto 5.5V supply witha
dual charge pump. The deviceis guaranteedto
runat data ratesof 250kbps while maintaining
RS-232 output levels.
The Auto-powerdown feature functions when
FORCEONis low and FORCEOFFis high. During
this modeof operation,if the device does not
sensea valid RS-232 signal, the driver outputs are
disabled.If FORCEOFFis set low, both drivers
and receivers (expert R2B) are shut off, and
supply currentis reducedto 1μA. Disconnecting
the serial portor turning off the peripheral drives
causes the auto-powerdown conditionto occur.
Auto-powerdown can be disabled when
FORCEON and FORCEOFF are high, and should done when drivinga serial mouse. With
Auto-powerdown enabled, the deviceis activated
automatically whena valid signalis appliedto any
receiver input.
Typical application arein notebook, subnotebook,
palmtop computers, battery-powered equipment,
hand-held equipment, peripherals and printers.
