DESCRIPTION/ORDERING INFORMATION
The MAX3223E 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 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 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 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.
