The HCC40160B, 40161B, 40162B, 40163B (extended temperature range) and HCF40160B, 40161B, 40162B, 40163B (intermediate temperature range) are monolithic integrated circuits, available 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 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 outputs 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-
