3-V To 5.5-V Multichannel RS-232 Line Driver/Receiver

The SN65C3243 and SN75C3243 consist 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). These devices provide 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, these devices include an always-active noninverting output (ROUT2B), which allows applications using the ring indicator to transmit data while the devices are powered down. The devices operate at data signaling rates up to 1 Mbit/s, and an increased slew-rate range of 24 V/s to 150 V/s.
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 devices do 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 A. 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 s. INVALID is low (invalid data) if all receiver input voltages are between ?0.3 V and 0.3 V for more than 30 s. Refer to Figure 5 for receiver input levels.
