MC100EL90
-3.3 V / -5V Triple ECL
Input to PECL Output
Translator
Description
The MC100EL90 is a triple ECL to PECL translator. The device
receives either 3.3 V or 5 V differential ECL signals, determined by
the VEE supply level, and translates them to standard +5 V differential
PECL output signals.
To accomplish the level translation, the EL90 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 plane.
Both VEE and VCC should be bypassed to ground via 0.01 mF
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.
The VBB pin, an internally generated voltage supply, is available to
this device only. For single-ended input conditions, the unused
differential input is connected to VBB as a switching reference voltage.
VBB may also rebias AC coupled inputs. When used, decouple VBB
and VCC via a 0.01ĂmF capacitor and limit current sourcing or sinking
to 0.5 mA. When not used, VBB should be left open.

NOTE: Device will meet the specifications after thermal equilibrium has been established when mounted in a test socket or printed circuit
board with maintained transverse airflow greater than 500 lfpm. Electrical parameters are guaranteed only over the declared
operating temperature range. Functional operation of the device exceeding these conditions is not implied. Device specification limit
values are applied individually under normal operating conditions and not valid simultaneously.
1. Output parameters vary 1:1 with VCC. VCC can vary ± 0.5 V.
2. Outputs are terminated through a 50 W resistor to VCC 2.0V.
