package and plastic micropackage.
HCC/HCF40160B, 40161B, 40162B
and
40163B
are 4-bit synchronous programmable counters. The
CLEAR function of the
HCC/HCF40162B
and
40163B
is synchronous and a low on the at the clear
CLEAR input sets all four outputs low on the next
positive CLOCK edge. The CLEAR function of the
HCC/HCF40160B
and
40161B
is asynchronous
and a low level at the CLEAR input sets all four out-
puts low regardless of the state of the CLOCK,
LOAD or ENABLE inputs. A low level at the LOAD
input disables the counter and causes the output to
agree with the set-up data after the next CLOCK
pulse regardless of the conditions of the ENABLE in-

plishing this function are two count-enable input
and a carry output (COUT). Counting is enable
when both PE and TE inputs are high. The TE input
is fed forward to enable COUT. This enable output
