2.5 V/3.3 V Any Level
Positive Input to
-2.5 V/-3.3 V LVNECL
Output Translator
Description
The NB100LVEP91 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
LVNECL output signals (2.5 V / 3.3 V).
To accomplish the level translation the LVEP91 requires three
power rails. The VCC pins should be connected to the positive power
supply, and the VEE pin should be connected to the negative power
supply. The GND pins 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 VCC/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 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 0.01 mF 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.

2. Pulse Skew = |tPLH tPHL|
3. Skews are valid across specified voltage range, part-to-part skew is for a given temperature.
