DESCRIPTION
The ST3243E device consists of 3 drivers, 5
receivers and a dual charge-pump circuit. The
device meets the requirements of 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 protected to ±8KV USING
IEC 1000-4-2 contact discharge and ±15KV using
the Human Body Model. The receiver R2 is
always active to implement a wake-up feature for
serial port.
The ST3243E has a proprietary low-dropout
transmitter output stage enabling true RS-232
performance from a 3.0V to 5.5V supply with a
dual charge pump. The device is guaranteed to
run at data rates of 250kbps while maintaining
RS-232 output levels.
The Auto-powerdown feature functions when
FORCEON is low and FORCEOFF is high. During
this mode of operation, if the device does not
sense a valid RS-232 signal, the driver outputs are
disabled. If FORCEOFF is set low, both drivers
and receivers (expert R2B) are shut off, and
supply current is reduced to 1
μ
A. Disconnecting
the serial port or turning off the peripheral drives
causes the auto-powerdown condition to occur.
Auto-powerdown
can
FORCEON and FORCEOFF are high, and should
be done when driving a serial mouse. With
Auto-powerdown enabled, the device is activated
automatically when a valid signal is applied to any
receiver input.
Typical application are in notebook, subnotebook,
palmtop computers, battery-powered equipment,
hand-held equipment, peripherals and printers.
