INFORMATION
The SN65C3222E and SN75C3222E 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).
The 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 500 kbit/s and a
maximum of 30-V/ms driver output slew rate.
which draws only 1 mA from the power supply. When the devices are powered down, the receivers remain active
while the drivers are placed in the high-impedance state. Also, during power down, the onboard charge pump is
disabled; V+ is lowered to VCC, and V– is raised toward GND. Receiver outputs also can be placed in the
high-impedance state by setting enable (EN) high. |
