LTC1334ISW#PBF

LTC1334 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 0.1µF 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 ICC supply current to 10µA. It is widely used in application such as low power RS485/RS422/RS232/EIA562 Interface, software-selectable multiprotocol interface port, cable repeaters, level translators etc.
