D ESC R I PT I O N 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-

cascading counter for n-bit synchronour application without additional gating. Instrumental in accomplishing this function are two c ount-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 ABSOLUTE M A XI M U M R A T I N G

produces a positive output pulse with a duration approximately equal to the positive portion of the Q1 output. This positive overflow carry pulse can be used to enable successive cascaded stages. Logic transitions at the PE or TE inputs may occur when the clock is either high or low.

Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for external periods may affect device reliability. * All voltage values are referred to VSS pin voltage.
