DESCRIPTION
The HCC40160B, 40161B, 40162B, 40163B (ex-
tended temperature range) and HCF40160B,
40161B, 40162B, 40163B (intermediate tempera-
ture range) are monolithic integrated circuits, avail-
able in 16-lead dual in line plastic or ceramic
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 issynchronous and a low onthe 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
