LTC1334CG Datasheet

erface - Drivers, Receivers, Transceivers


The LTC1334CG 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 0.1mF 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 10mA. LTC1334CG Features • Four RS232 Transceivers or Two RS485 Transceivers on One Chip• Operates from a Single 5V Supply• Withstands Repeated ±10kV ESD Pulses• Uses Small Charge Pump Capacitors: 0.1mF• Low Supply Current: 8mA Typical• 10mA Supply Current in Shutdown• 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 LTC1334CG Applications • Low Power RS485/RS422/RS232/EIA562 Interface• Software-Selectable Multiprotocol Interface Port• Cable Repeaters• Level Translators
