The MC100LVEL/EL90 is a triple ECL to PECL translator. The device
receives either standard or low voltage differential ECL signals and
translates them to either standard or low voltage differential PECL output
signals. The LVEL device can handle the low voltage signals while the EL
device is designed for the standard signals. It is possible to have low
voltage signals on one side and standard signals on the other if the
LVEL90 is used.

A VBB output is provided for interfacing with single ended ECL signals
at the input. If a single ended input is to be used the VBB output should be
connected to the D input. The active signal would then drive the D input.
When used the VBB output should be bypassed to ground via a 0.01
μ
F
capacitor. The VBB output is designed to act as the switching reference
for the EL90 under single ended input switching conditions, as a result
this pin can only source/sink up to 0.5mA of current.
To accomplish the level translation the EL/LVEL90 requires three
power rails. The VCC supply should be connected to the positive supply,
and the VEE pin should be connected to the negative power supply. The
GND pins as expected are connected to the system ground plain. Both
VEE and VCC should be bypassed to ground via 0.01
μ
F capacitors.
Under open input conditions, the D input will be biased at VEE/2 and
the D input will be pulled to VEE. This condition will force the Q output to a
LOW, ensuring stability.
