LTC1385CG#PBF

LTC1385 is a 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 only 200µA in the unloaded condition. In the driver disable 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. It is s fully compliant with all data rate and overvoltage EIA/TIA-562 specifications. The transceiver can operate up to 120Kbaud with a 1000pF, 3Kohm load. Both driver outputs and receiver inputs can be forced to ±25V without damage, and can survive multiple ±10KV ESD strikes. It is used in application such as notebook computers, palmtop computers etc.

• Output overvoltage does not force current back into supplies
• Pin compatible with LT1180A
• Output voltage swing is 4.5V typical at (VCC = 3.3V)
• Output short-circuit current is ±10mA typical at (VOUT = 0V,VCC = 3.3V)
• Hysteresis is 0.4V typical at (VCC = 3.3V)
• Operating temperature is 0°C to 70°C
• Package style is 20-lead SSOP
