ORDERING INFORMATION
The TRSF3222E 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 TRSF3222E 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 TRSF3222E
operates at typical data signaling rates up to
1000 kbit/s and is an improved drop-in replacement
for industry-popular '3222 two-driver, two-receiver
functions.
which draws only 1 μ A from the power supply. When the device is 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 V
CC
, and V– is raised toward GND. Receiver outputs also can be placed in the
high-impedance state by setting enable ( EN) high.
