MC100EP91
2.5 V/3.3 V Any Level
Positive Input to
-3.3 V/-5.5 V NECL
Output Translator
Description
The MC100EP91 is a triple any level positive input to NECL output
translator. The device accepts LVPECL, LVTTL, LVCMOS, HSTL,
CML or LVDS signals, and translates them to differential NECL
output signals (−3.0 V/−5.5 V).
To accomplish the level translation the EP91 requires three power
rails. The V
CC
pins should be connected to the positive power supply,
and the V
EE
pin should be connected to the negative power supply.
The GND pins are connected to the system ground plane. Both V
EE
and V
CC
should be bypassed to ground via 0.01 mF capacitors.
Under open input conditions, the D
input will be biased at V
CC
/2
and the D input will be pulled to GND. These conditions will force the
Q outputs to a low state, and Q outputs to a high state, which will
ensure stability.
The V
BB
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
BB
as a switching reference voltage.
V
BB
may also rebias AC coupled inputs. When used, decouple V
BB
and V
CC
via a 0.01 mF capacitor and limit current sourcing or sinking
to 0.5 mA. When not used, V
BB
should be left open.
