3.3V / 5VECL 8-Bit
Synchronous Binary
Up Counter
The MC10/100EP016 is a high–speed synchronous, presettable,
cascadeable 8–bit binary counter. Architecture and operation are the
same as the MC10E016 in the ECLinPS
family.
The counter features internal feedback to TC gated by the TCLD
(Terminal Count Load) pin. When TCLD is LOW (or left open, in
which case it is pulled LOW by the internal pulldowns), the TC
feedback is disabled, and counting proceeds continuously, with TC
going LOW to indicate an all–one state. When TCLD is HIGH, the TC
feedback causes the counter to automatically reload upon TC = LOW,
thus functioning as a programmable counter. The Qn outputs do not
need to be terminated for the count function to operate properly. To
minimize noise and power, unused Q outputs should be left
unterminated.
COUT and COUT have been added to allow cascading to be done
without adding external components. COUT and COUT should only
be connected to cascaded MC10/100EP016 inputs such as CE or PE.
Only TC should be used for a counter chain count output pin.
A differential clock input has also been added to improve
performance.
The 100 Series contains temperature compensation.
