DESCRIPTION
The STLV3243E device consists of 3 drivers, 5
receivers and a dual charge-pump circuit. All
transmitter outputs and receiver inputs are
protected up 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
device is guaranteed to run at data rates of
250kbps while maintaining RS-562 output levels.
The Auto-powerdown feature operates when
FORCEON is low and FORCEOFF is high. During
this operation mode, if the device does not sense
a valid RS-562 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 1µA. Disconnecting
the serial port or turning off the peripheral drives
causes the auto-powerdown condition to occur.
Auto-powerdown can be disabled when
FORCEON and FORCEOFF are high, and this
should be done when driving a serial mouse. With
Auto-powerdown enabled, the device is
automatically activated when a valid signal is
applied to any receiver input.
Typical applications are notebooks, PDAs,
smart-phones, hand-held equipment, palmtop
computers, peripherals, battery-powered
equipment, and printers.
