The MC10E/100E016 is a high-speed synchronous, presettable,
cascadable 8-bit binary counter. Architecture and operation are the same
as the MC10H016 in the MECL 10H family, extended to 8-bits, as shown
in the logic symbol.
The counter features internal feedback of 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 pull-downs), 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.
