в–  DESCRIPTIO The LTC В®1334 is a low power CMOS bidirectional transceiver 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 0.1ВµF capacitors to generate
boosted positive and negative supplies, allowing the RS232
drivers to meet the RS232 В±5V output swing requirement
with only a single 5V supply. A shutdown mode reduces
the ICC supply current to 10ВµA. Four RS232 Transceivers or Two RS485
Transceivers on One Chip
Operates from a Single 5V Supply
Withstands Repeated В±10kV ESD Pulses …
