LTC1385
3.3V Low Power
EIA/TIA-562 Transceiver
S
FEATURE
D
The LTC1385 is an ultra-low power, 2-driver/2-receiver
EIA/TIA-562 transceiver which operates from a single
3.3V supply. The charge pump requires only four space-
saving 0.1
μ
F capacitors.
The transceiver operates in one of three modes: Normal,
Driver Disable or Shutdown. In the Normal mode, I
CC
is
only 200
μ
A in the unloaded condition. In the Driver Disable
mode, the charge pump is turned off, the driver outputs
are forced into three-state, both receivers are kept active,
and I
CC
drops to 35
μ
A. In the Shutdown mode, everything
is turned off and I
CC
drops to 0.2
μ
A.
The LTC1385 is fully compliant with all data rate and
overvoltage EIA/TIA-562 specifications. The transceiver
can operate up to 120kbaud with a 1000pF, 3k
load.
Both driver outputs and receiver inputs can be forced to
±
25V without damage, and can survive multiple
±
10kV
ESD strikes.
