DESCRIPTIO
The LTC
RS232 transceiver that operates from a single 5V
supply. The charge pump requires only four space-
saving 0.1µF capacitors.
The transceiver operates in one of two modes, Normal
and Shutdown. In the Normal mode, I
with the driver outputs unloaded. In the Shutdown
mode, the charge pump is turned off, the driver outputs
are forced into three-state, both receivers are off and
I
The LTC1382 is fully compliant with all data rate and
overvoltage RS232 specifications. The transceiver can
operate up to 120kbaud with a 2500pF, 3kΩ load. Both
driver outputs and receiver inputs can be forced to
±25V without damage and can survive multiple ±10kV
ESD strikes.
