MC14518B, MC14520B

Dual Up Counters

counter are constructed with MOS P−channel and N−channel

enhancement mode devices in a single monolithic structure. Each

consists of two identical, independent, internally synchronous 4−stage

counters. The counter stages are type D flip−flops, with interchangeable

Clock and Enable lines for incrementing on either the positive−going or

negative−going transition as required when cascading multiple stages.

Each counter can be cleared by applying a high level on the Reset line.

In addition, the MC14518B will count out of all undefined states within

two clock periods. These complementary MOS up counters find

primary use in multi−stage synchronous or ripple counting applications

requiring low power dissipation and/or high noise immunity.

Features

•

Maximum ratings are those values beyond which device damage can occur.

Maximum ratings applied to the device are individual stress limit values (not

normal operating conditions) and are not valid simultaneously. If these limits are

exceeded, device functional operation is not implied, damage may occur and

reliability may be affected.

applications of any voltage higher than maximum rated voltages to this
