MC100EP16VC
3.3V / 5V ECL Differential
Receiver/Driver with High
Gain and Enable Output
Description
The EP16VC is a differential receiver/driver. The device is
functionally equivalent to the EP16 and LVEP16 devices but with high
gain and enable output.
The EP16VC provides an EN input which is synchronized with the
data input (D) signal in a way that provides glitchless gating of the
QHG and QHG outputs.
When the EN signal is LOW, the input is passed to the outputs and
the data output equals the data input. When the data input is HIGH and
EN goes HIGH, it will force the Q
HG
LOW and the Q
HG
HIGH on the
next negative transition of the data input. If the data input is LOW
when the EN goes HIGH, the next data transition to a HIGH is ignored
and Q
HG
remains LOW and Q
HG
remains HIGH. The next positive
transition of the data input is not passed on to the data outputs under
these conditions. The Q
HG
and Q
HG
outputs remain in their disabled
state as long as the EN input is held HIGH. The EN input has no
influence on the Q output and the data input is passed on (inverted) to
this output whether EN is HIGH or LOW. This configuration is ideal
for crystal oscillator applications where the oscillator can be free
running and gated on and off synchronously without adding extra
counts to the output.
The V
BB
/D pin is internally dedicated and available for differential
interconnect. V
BB
/D may rebias AC coupled inputs. When used,
decouple V
BB
/D and V
CC
via a 0.01
mF
capacitor and limit current
sourcing or sinking to 1.5 mA. When not used, V
BB
/D should be left
open.
The 100 Series contains temperature compensation.
