LTC1347
5V Low Power RS232
3-Driver/5-Receiver Transceiver
with 5 Receivers Active
in Shutdown
S
FEATURE
D
The LTC1347 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.
In Shutdown mode, all five receivers are kept alive and the
supply current is 80
μ
A. All RS232 outputs assume a high
impedance state in Shutdown and with the power off.
The LTC1347 is fully compliant with all data rate and
overvoltage RS232 specifications. The transceiver can
operate up to 120kbaud with a 2500pF, 3k
load. Both
driver outputs and receiver inputs can be forced to
±
25V
without damage, and can survive multiple
±
10kV ESD
strikes.
