DESCRIPTION

The DS90LV012A and DS90LT012A accept low voltage (350 mV typical) differential input signals and translates them to 3V CMOS output levels. The receivers also support open, shorted, and terminated (100) input fail-safe. The receiver output will be HIGH for all fail-safe conditions. The DS90LV012A has a pinout designed for easy PCB layout. The DS90LT012A includes an input line termination resistor for point-to-point applications.
The DS90LV012A and DS90LT012A, and companion LVDS line driver provide a new alternative to high power PECL/ECL devices for high speed interface applications.
