These products are designed for applications requiring high-speed, low-power consumption and low noise generation. A low voltage TTL/CMOS input level is translated by the device into a low-voltage (350mV) differential output signal. Exclusive to the PI90LV031A quad driver is a power-down mode that Tri-states the outputs and places the device in a low-power idle state (13mW typical).

The transmission media can be printed circuit board traces, backplanes, or cables. The PI90LV031A, PI90LV027A, PI90LV017A and companion line receivers (PI90LV032A, PI90LV028A, and PI90LV018A) provide new alternatives to RS-232, PECL, and ECL devices for high-speed, pointto-point interface applications. 1 PS8422A 10/08/99 PI90LV031A / PI90LV027A / PI90LV017A 3V LVDS High-Speed Differential Line Drivers 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012 Function Tables PI90LV031A Pin Descriptions Enable s Input Outputs Name D e s cription EN EN* DIN DOUT+ DOUT- DIN TTL/CMO S driver input pins H X H H L DO+ Non- inverting driver output pins H X L L H DO- Inverting driver output pins X L H H L GND Ground pin X L L L H VCC Positive power supply pin, +3.3V ±10% L H X Z Z PI90LV027A Recommended Operating Conditions Input Outputs D IN D OUT+ D OUT- H H L L L H M in.
