MC14520BDWR2G

Counter Dividers Overview

The MC14520BDWR2G is a dual binary counter from the MC14520B series, manufactured by onsemi. It consists of two independent, internally synchronous 4-stage counters constructed with CMOS technology. The device operates within a supply voltage range of 3.0 Vdc to 18 Vdc and supports an operating temperature range of -55°C to +125°C. It features interchangeable Clock and Enable lines for incrementing on either positive-going or negative-going transitions. Each counter can be cleared by applying a high level on the Reset line. The component is housed in a 16-pin SOIC Wide (DW) package.

Counter Dividers Feature Summary

• Internally synchronous design ensures high internal and external speeds
• Logic edge-clocked architecture allows 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
• Circuits requiring high noise immunity

Counter Dividers Procurement Notes

Verify the specific ordering suffix 'DWR2G' corresponds to the SOIC-16 WB tape and reel packaging configuration. Confirm RoHS compliance status as indicated by the 'G' suffix. Ensure the procurement matches the active manufacturing status, noting that related variants like the tube version may have different availability or discontinuation statuses.

Counter Dividers Selection Notes

Select this component when a dual binary counter is required instead of BCD counting. Verify compatibility with logic families capable of driving two Low-power TTL loads or one Low-power Schottky TTL load. Consider the wide operating temperature range for harsh environments. Ensure the application utilizes the asynchronous reset functionality for clearing counter states.

Counter Dividers Part Context

This part belongs to the MC145xxB family of complementary MOS logic devices. It is functionally paired with the MC14518B, which offers dual BCD counting capabilities. Both share identical pinouts and electrical characteristics but differ in their counting sequences. The MC14520B specifically implements binary counting logic using D flip-flops.
