Description
The PI90LVx386 family consists of sixteen differential line receivers
with 3-state outputs that implement Low-Voltage Differential
Signaling (LVDS). Any of the differential receivers will provide a
valid logical output state with a 100mV differential input voltage
within the input common-mode voltage range that allows 0 to 3V of
ground potential difference between two LVDS nodes. The indepen-
dent EN pins can be used to place the outputs in either a normal logic
state (high or low logic levels) or a high-impedance state. In high-
impedance state, outputs neither load nor drive the bus lines.
The intended application of these devices, and their signaling
techniques, is for point-to-point baseband data transmission over
controlled impedance media of approximately 100-ohms with a
100-Ohm termination resistor. The PI90LVT386 integrates the termi-
nating resistors while the PI90LV386 requires external resistors.
The transmission media may be printed circuit board traces,
backplanes, or cables. The PI90LV386's 16 receivers integrated into
the same substrate allow precise timing alignment.
These parts are characterized for operation from 40C to 85C.

Over Operating Free-Air Temperature
(unless otherwise noted)
Stresses beyond those listed under "Absolute Maximum Ratings" may
cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond
those indicated under "Recommended Operating Conditions" is not
implied. Exposure to Absolute-Maximum-Rated conditions for extended
periods may affect device reliability.
Notes:
