MC14518B
DUAL UP COUNTERS
-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. Diode Protection on All Inputs Supply Voltage Range = 3.0 Vdc to 18 Vdc Internally Synchronous for High Internal and External Speeds Logic Edge–Clocked Design — Incremented on Positive Transition of
Clock or Negative Transition on Enable Capable of Driving Two Low–power TTL Loads or One Low–power
Schottky TTL Load Over the Rated Temperature Range
