DESCRIPTION
The
M74HC192
is
an
high
speed
CMOS
SYNCRONOUS
UP/DOWN
DECADE
COUNTERS fabricated with silicon gate C2MOS
technology.
The counter has two separate clock inputs, an UP
COUNT input and a DOWN COUNT input. All
outputs
of
the
flip-flop
are
simultaneously
triggered on the low to high transition of either
clock while the other input is held high. The
direction of counting is determined by which input
is clocked. This counter may be preset by entering
the desired data on the DATA A, DATA B, DATA
C, and DATA D input. When the LOAD input is
taken low the data is loaded independently of
either clock input. This feature allows the counters
to be used as divide-by-n counters by modifying
the count length with the preset inputs. In addition
the
counter
can
also
be
cleared.
This
is
accomplished by inputting a high on the CLEAR
input. All 4 internal stages are set to low
independently of either COUNT input. Both a
BORROW and CARRY output are provided to
enable cascading of both up and down counting
functions. The BORROW output produces a
negative going pulse when the counter underflows
and the CARRY outputs a pulse when the
counters overflows. The counter can be cascaded
by connection the CARRY and BORROW outputs
of one device to the COUNT UP and COUNT
DOWN inputs, respectively, of the next device.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
