5V Low Power RS232
3-Driver/5-Receiver Transceiver
S
FEATURE
D
The LTC1337 is a 3-driver/5-receiver RS232 transceiver
with very low supply current. In the no load condition, the
supply current is only 300
μ
A. The charge pump only
requires four 0.1
μ
F capacitors and can supply up to 12mA
of extra current to power external circuitry.
In SHUTDOWN mode, the supply current is further re-
duced to 1
μ
A. All RS232 outputs assume a high imped-
ance 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//3k
load. Both
driver outputs and receiver inputs can be forced to
±
25V
without damage, and can survive multiple
±
10kV ESD
strikes.
