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 communication 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

µA. 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 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.
