Product Overview

The LTC1334ISW#PBF is a low power CMOS bidirectional Multiprotocol 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. The RS232 transceiver is in full compliance with RS232 specifications. The RS485 transceivers are in full compliance with RS485 and RS422 specifications. All interface drivers feature short-circuit and thermal shutdown protection. 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.
  • 0.1µF Uses small charge pump capacitors
  • Self-testing capability in loopback mode
  • Power-up/down glitch-free outputs
  • Driver maintains high impedance in three-state, shutdown or with power OFF
  • Thermal shutdown protection
  • Receiver inputs can withstand ±25V
