Description
General part information
TRS3223-Q1 Series
The TRS3223E 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 meets the requirements of TIA/EIA-232-F and 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 typical data signaling rates up to 500 kbit/s and a maximum of 30-V/µs driver output slew rate.
Flexible control options for power management are available when the serial port is 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 are disabled. IfFORCEOFFis set low and EN is high, both drivers and receivers are shut off, and the supply current is reduced to 1 mA. Disconnecting the serial port or turning off the peripheral drivers causes auto-powerdown to occur. Auto-powerdown can be disabled when FORCEON andFORCEOFFare high. With auto-powerdown enabled, the device is activated automatically when a valid signal is applied to any receiver input. TheINVALIDoutput is used to notify the user if an RS-232 signal is present at any receiver input.INVALIDis 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.INVALIDis 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.
