TRSF232433- to 5.5-V multichannel 250kbps RS-232 line driver/receiver with +/-15-kV ESD protection | Interface | 1 | Obsolete | The TRSF23243 consists of two ports, each containing three line drivers and 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 meets the requirements of TIA/EIA-232-F and provides the electrical interface between an asynchronous communication controller and the serial-port connector. This combination of drivers and receivers matches that needed for two typical serial ports used in an IBM PC/AT, or compatible. 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 (ROUT2) per port, 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 250 kbit/s and a maximum of 30-V/µs driver output slew-rate.
Flexible control options for power management are available when either or both serial ports are inactive. The auto-powerdown feature functions when FORCEON is low andFORCEOFFis high. During this mode of operation, if the device does not sense a valid RS-232 signal, the driver outputs of its respective port are disabled. IfFORCEOFFis set low, both drivers and receivers (exceptROUT2) 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 andFORCEOFFare high and should be done when driving a serial mouse. With auto-powerdown enabled, the RS-232 port is activated automatically when a valid signal is applied to any respective receiver input. TheINVoutput is used to notify the user if an RS-232 signal is present at any receiver input.INVis 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.INVis low (invalid data) if all receiver input voltages are between -0.3 V and 0.3 V for more than 30 µs.
