The M54/74HC192/193 are ahigh speed CMOSSYN-
CHRONOUS UP/DOWN DECADE COUNTERS fab-
ricated in silicon gate C2MOS technology. They have
the same high speed performance of LSTTL combined
with true CMOS low power consumption. 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 transi-
tion of either clock while the other input isheld 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 pro-
duces a negative going pulse when the counter under-
flows and the CARRY outputs a pulse when the
counter overflows. The counter can be cascaded by
connecting 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.
