LTC1334
Single 5V RS232/RS485
Multiprotocol Transceiver
The LTC
1334 is a low power CMOS
bidirectional trans-
ceiver featuring two
reconfigurable interface ports. It can
be configured as two RS485 differential ports, as two dual
RS232 single-ended ports or as one RS485 differential
port and one dual RS232 single-ended port. An onboard
charge pump requires four 0.1
μ
F capacitors to generate
boosted positive and negative supplies, allowing the RS232
drivers to meet the RS232
±
5V output swing requirement
with only a single 5V supply. A shutdown mode reduces
the I
CC
supply current to 10
μ
A.
The RS232 transceivers are in full compliance with RS232
specifications. The RS485 transceivers are in full compli-
ance with RS485 and RS422 specifications. All interface
drivers feature short-circuit and thermal shutdown pro-
tection. An enable pin allows RS485 driver outputs to be
forced into high impedance, which is maintained even
when the outputs are forced beyond supply rails or power
is off. Both driver outputs and receiver inputs feature
±
10kV ESD protection. A loopback mode allows the driver
outputs to be connected back to the receiver inputs for
diagnostic self-test.
