LTC1334CG#PBF, RS-232 Interface IC 1x 5V RS232/RS485 Multiprotocol Tran

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 on-board 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. • Withstands repeated ±10kV ESD pulses• Low supply current is 8mA typ• 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• Slew rate is 30V/µs max• Operating temperature is 0°C to 70°C• Packaging style is 28-lead plastic SSOP
