MC74HC4020ADR2G

Counter Dividers Overview

The MC74HC4020ADR2G is a 14-stage binary ripple counter manufactured by onsemi in the 74HC series. It utilizes high-performance silicon-gate CMOS technology and operates within a supply voltage range of 2.0 V to 6.0 V. The device contains 14 master-slave flip-flops with 12 stages brought out to pins, providing outputs that divide the clock frequency by powers of two. It features asynchronous active-high reset functionality and negative-edge triggering. Maximum clock frequencies reach 50 MHz at 6.0 V, with propagation delays varying from 25 ns to 96 ns depending on voltage.

Counter Dividers Feature Summary

• Contains 14 master-slave flip-flops with 12 accessible output stages for binary counting
• Features asynchronous active-high reset to force all outputs low
• Negative-edge triggered clock input advances the counter state
• Outputs directly interface with CMOS, NMOS, and TTL logic families

Counter Dividers Applications

• Time-base generator circuits
• Frequency division applications
• Binary counting sequences

Counter Dividers Procurement Notes

Verify the specific package suffix 'D' corresponds to the SOIC-16 form factor required for your design. Confirm the 'R2G' designation indicates tape and reel packaging compatible with automated assembly equipment. Ensure the component meets RoHS compliance standards if applicable to your manufacturing process.

Counter Dividers Selection Notes

Select this component when a 14-bit binary count is required with minimal external gating. The HC series offers compatibility with standard CMOS outputs and LSTTL loads via pull-up resistors. Consider the ripple delay characteristics for timing-sensitive designs, as decoded signals may require gating with the clock signal to avoid spikes.

Counter Dividers Part Context

This part belongs to the MC74HC4020A family of 14-stage binary counters. It shares pinout compatibility with the standard CMOS MC14020B. The device is designed for general-purpose digital counting applications requiring high noise immunity and low input current characteristics typical of CMOS technology.
