Operates from a Single 3.3V Supply  
Low Supply Current: ICC = 200µA  
ICC = 35µA in Driver Disable Mode  
ICC = 0.2µA in Shutdown Mode  
ESD Protection Over ±10kV  
Uses Small Capacitors: 0.1µF  
Operates to 120kBaud  
Output Overvoltage Does Not Force Current  
Back into Supplies  
EIA/TIA-562 I/O Lines Can Be Forced to ±25V  
Without Damage  
Pin Compatible with LT1180A  
The LTC1385 is an ultra-low power, 2-driver/2-receiver  
EIA/TIA-562 transceiver which operates from a single  
3.3V supply. The charge pump requires only four space-  
saving 0.1µF capacitors.  
The transceiver operates in one of three modes: Normal,  
Driver Disable or Shutdown. In the Normal mode, ICC is  
only200µAintheunloadedcondition.IntheDriverDisable  
mode, the charge pump is turned off, the driver outputs  
are forced into three-state, both receivers are kept active,  
and ICC drops to 35µA. In the Shutdown mode, everything  
is turned off and ICC drops to 0.2µA.  
The LTC1385 is fully compliant with all data rate and  
overvoltage EIA/TIA-562 specifications. The transceiver  
can operate up to 120kbaud with a 1000pF, 3kload.  
Both driver outputs and receiver inputs can be forced to  
±25V without damage, and can survive multiple ±10kV  
ESD strikes.
