MC100EL91
5 V Triple PECL Input to
-5 V ECL Output Translator
Description
The MC100EL91 is a triple PECL input to ECL output translator.
The device receives standard voltage differential PECL signals,

determined by the V supply level, and translates them to differential
CC
5 V ECL output signals. (For translation of LVPECL to 3.3 V ECL
output, see MC100LVEL91.)
To accomplish the level translation, the EL91 requires three power
rails. The V supply should be connected to the positive supply, and
CC
the V pin should be connected to the negative power supply. The
EE
GND pins are connected to the system ground plane. Both V and

V should be bypassed to ground via 0.01F capacitors.
CC
DW SUFFIX
Under open input conditions, the D input will be biased at V /2
CC

and the D input will be pulled to GND. This condition will force the Q
output to a low, ensuring stability.
The V pin, an internally generated voltage supply, is available to

this device only. For single-ended input conditions, the unused
differential input is connected to V as a switching reference voltage.

V may also rebias AC coupled inputs. When used, decouple V

and V via a 0.01F capacitor and limit current sourcing or sinking

to 0.5 mA. When not used, V should be left open.
