DESCRIPTION

The M54/74HC192/193 are ahigh speed CMOSSYN-

CHRONOUS UP/DOWN DECADE COUNTERS fab-

ricated in silicon gate C

MOS 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.
