LTC1327 3.3V Micropower EIA/TIA-562 Transceiver Features s s s s s s s s DESCRIPTIO s s Low Supply Current 300µA 0.2µA Supply Current in SHUTDOWN ESD Protection ±10k V Operates From a Single 3.3V Supply Uses Small Capacitors 0.1µF Operates To 120k Baud Three-State Outputs are High Impedance When Off Output Overvoltage Does Not Force Current Back Into Supplies EIA/TIA-562 I/O Lines Can Be Forced to ± 25V Without Damage Flowthrough Architecture The LTC1327 is an advanced low power, three-driver/fivereceiver EIA/TIA-562 transceiver. In the no load condition, the supply current is only 300µA. The charge pump only requires four 0.1µF capacitors. In SHUTDOWN mode, the supply current is further reduced to 0.2µA. All EIA/TIA-562 outputs assume a high impedance state in SHUTDOWN and with the power off. The LTC1327 is fully pliant with all data rate and overvoltage EIA/TIA-562 specifications. The transceiver can operate up to 120k Baud with a 1000p F//3kΩ load. Both driver outputs and receiver inputs can be forced to ± 25V without damage, and can survive multiple ±10k V ESD strikes.
