MC14520BCPG

Counter Dividers Overview

The MC14520BCPG is a dual binary counter from the onsemi 4000 series, housed in a 16-pin PDIP package. It contains two independent internally synchronous 4-stage counters constructed with CMOS technology. The device operates within a supply voltage range of 3 V to 18 V and supports an operating temperature range of -55 °C to +125 °C. Each counter features interchangeable Clock and Enable lines for incrementing on either positive-going or negative-going transitions. Counters are cleared by applying a high level on the Reset line.

Counter Dividers Feature Summary

• Internally synchronous architecture designed for high internal and external speeds
• Logic edge-clocked design allowing incrementing on positive clock or negative enable transitions
• Interchangeable Clock and Enable lines facilitate cascading multiple stages
• Diode protection provided on all inputs

Counter Dividers Applications

• Multi-stage synchronous counting applications
• Ripple counting applications requiring low power dissipation
• Applications requiring high noise immunity

Counter Dividers Procurement Notes

Verify the specific suffix against official documentation, as ordering codes may indicate variations in packaging or automotive qualification. Confirm current availability status directly with the manufacturer, as some variants in this family have been discontinued. Ensure the selected component meets the required environmental and control change specifications for the intended deployment.

Counter Dividers Selection Notes

Select this component when a dual binary counter with flexible triggering is required. The interchangeable Clock and Enable lines simplify circuit design for cascaded configurations. Verify that the load requirements align with the drive capabilities specified in the datasheet. Consider the PDIP package constraints if surface-mount alternatives are preferred.

Counter Dividers Part Context

This part belongs to the MC145xxB series of complementary MOS logic devices. It serves as the binary counterpart to the MC14518B BCD counter within the same monolithic structure. Both devices share identical pinouts and electrical characteristics, differing only in their counting sequence (binary versus BCD).

Counter Dividers Replacement Considerations

The MC14518B is functionally compatible regarding pinout and electrical specs but counts in BCD rather than binary. Other generic 4000-series dual counters may require verification of trigger polarity and reset logic compatibility.
