INFORMATION
The SN65C3223E and SN75C3223E consist 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).
These
devices
meet
the
requirements
of
TIA/EIA-232-F and 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. The devices operate at
typical data signaling rates up to 1000 kbit/s.
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 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 devices are 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 the receiver input voltage is between –0.3 V and 0.3 V for more than
30
s. Refer to Figure 4 for receiver input levels.
