LTC1385  
3.3V Low Power  
EIA/TIA-562 Transceiver  
U
FEATURES  
DESCRIPTIO  
The LTC®1385 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.  
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  
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.  
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 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.
