MOTOROLA MC14518-520B Dual up counter Datasheet

 SEMICONDUCTOR TECHNICAL DATA
The MC14518B dual BCD counter and the MC14520B dual binary 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.

This device contains protection circuitry to
guard against damage due to high static
voltages or electric fields. However, precautions must be taken to avoid applications of
any voltage higher than maximum rated voltages to this high–impedance circuit. For proper
operation, Vin and Vout should be constrained
to the range VSS
(Vin or Vout)
VDD.
Unused inputs must always be tied to an
appropriate logic voltage level (e.g., either VSS
or VDD). Unused outputs must be left open.
