LTC1386IS#TRPBF Analog Devices

LTC1386 3.3V Low Power EIA/TIA562 Transceiver FEATURES DESCRIPTIO Operates from a Single 3.3V Supply The LTC 1386 is an ultra-low power 2-driver/2-re- Low Supply Current: I = 200A ceiver EIA/TIA562 transceiver that operates from a CC ESD Protection Over 10kV single 3.3V supply. The charge pump requires only four Available in 16-Pin SOIC Narrow Package space-saving 0.1F capacitors. The supply current Uses Small Capacitors: 0.1F (I ) of the transceiver is only 200A with driver out- CC Operates to 120kBaud puts unloaded. Output Overvoltage Does Not Force Current The LTC1386 is fully compliant with all data rate and Back into Supplies overvoltage EIA/TIA562 specifications. The transceiver EIA/TIA562 I/O Lines Can Be Forced to 25V can operate up to 120kbaud with a 1000pF, 3k load. Without Damage Both driver outputs and receiver inputs can be forced to Pin Compatible with LT1181A 25V without damage and can survive multiple 10kV ESD strikes.
