DESCRIPTION/ORDERING INFORMATION

The TRSF3223 consists of two line drivers, two line receivers, and a dual charge-pump circuit with ±15-kV ESD

protection pin to pin (serial-port connection pins, including GND). The 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. The device operates at data

signaling rates up to 1 Mbit/s and a driver output slew rate 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 and enable (EN) is high, both drivers and receivers are shut off, and the supply current is reduced to

1 μA. Disconnecting the serial port or turning off the peripheral drivers causes auto-powerdown to occur.

Auto-powerdown can be disabled when FORCEON and FORCEOFF are high. 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 the receiver input voltage is between –0.3 V and 0.3 V for more than

30 μs. Refer to Figure 4 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.
