Product Summary

The MC14520BCL dual binary counter is 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 MC14520BCL 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.

Parametrics

MC14520BCL absolute maximum ratings: (1)DC Supply Voltage:-0.5 to + 18.0 V; (2)Input or Output Voltage (DC or Transient): 0.5 to VDD + 0.5 V; (3)Input or Output Current (DC or Transient), per Pin:± 10 mA; (4)Power Dissipation, per Package:500 mW; (5)Storage Temperature:-65 to + 150℃; (6)Lead Temperature (8–Second Soldering):260℃.

Features

MC14520BCL features: (1)Diode Protection on All Inputs; (2)Supply Voltage Range = 3.0 Vdc to 18 Vdc; (3)Internally Synchronous for High Internal and External Speeds; (4)Logic Edge–Clocked Design - Incremented on Positive Transition of Clock or Negative Transition on Enable; (5)Capable of Driving Two Low–power TTL Loads or One Low–power Schottky TTL Load Over the Rated Temperature Range.
