3-Driver/5-Receiver Transceiver
DESCRIPTIO
The LTC
with very low supply current. In the no load condition, the
supply current is only 300µA. The charge pump only
requires four 0.1µF capacitors and can supply up to 12mA
of extra current to power external circuitry.
In Shutdown mode, the supply current is further reduced
to 1µA. All RS232 outputs assume a high impedance state
in Shutdown and with the power off.
The LTC1337 is fully compliant with all data rate and
overvoltage RS232 specifications. The transceiver can
operate up to 120k baud with a 1000pF// 3kΩ load. Both
driver outputs and receiver inputs can be forced to ±25V
without damage, and can survive multiple ±10kV ESD
strikes.
