Description
Features
SK10/100E116
Quint Differential
Line Receiver
The SK10/100E116 is a quint differential line receiver
designed for use in new, high-performance ECL systems.
The receiver design features clamp circuitry to cause a
defined output state if both the inverting and non-inverting
inputs are left open; in this case the Q output goes low,
while the Q* output goes high. This feature makes the
device ideal for twisted pair applications.
If both inverting and non-inverting inputs are at an equal
potential of >–2.9V, the receiver does not go to a defined
state, but rather shares current in normal differential
amplifier fashion, producing output voltage levels midway
between high and low. This may even cause the device to
oscillate.

Pin Description
The SK10/100E116 provides VBB output for either single-
ended use or as a DC bias for AC coupling to the device.
The VBB output pin should be used only as a DC bias for
the E116 as its current sink/source capability is limited.
Whenever used, the VBB pin should be bypassed to VCC
via a 0.01 µF capacitor.
