DESCRIPTION/ORDERING INFORMATION

The TRSF3243 consists of three line drivers, five line receivers, and a dual charge-pump circuit with ±15-kV ESD

protection pin to pin (serial-port connection pins, including GND). This device provides the electrical interface

between an asynchronous communication controller and the serial-port connector. The charge pump and four

small external capacitors allow operation from a single 3-V to 5.5-V supply. In addition, this device includes an

always-active noninverting output (ROUT2B), which allows applications using the ring indicator to transmit data

while the device is powered down. The device operates at data signaling rates up to 1 Mbit/s and an increased

slew-rate range of 24 V/µs to 150 V/µs.

Flexible control options for power management are available when the serial port is inactive. 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 (except ROUT2B) are shut off, and the supply current is reduced to 1 µA.

Disconnecting the serial port or turning off the peripheral drivers 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. The INVALID output is used to notify the user if an RS-232 signal is present at any

receiver input. INVALID is high (valid data) if any receiver input voltage is greater than 2.7 V or less than –2.7 V

or has been between –0.3 V and 0.3 V for less than 30 µs. INVALID is low (invalid data) if all receiver input

voltages are between –0.3 V and 0.3 V for more than 30 µs. Refer to Figure 5 for receiver input levels.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
