CD74HC4020MT

Counter Dividers Overview

The CD74HC4020MT is a high-speed CMOS logic component manufactured by Texas Instruments, functioning as a 14-stage binary ripple counter. It operates within a supply voltage range of 2.0 V to 6.0 V and features an asynchronous master reset input that clears all stages when driven HIGH. The device includes clamp diodes on its inputs, allowing for current-limiting resistors to interface with voltages exceeding VCC. It provides twelve buffered parallel outputs (Q0, Q3 through Q13) and advances on the HIGH-to-LOW transition of the clock signal.

Counter Dividers Feature Summary

• Provides 14-stage binary counting capability using static toggle flip-flops
• Features an overriding asynchronous master reset input independent of the clock state
• Includes input clamp diodes to facilitate interfacing with voltages exceeding VCC

Counter Dividers Applications

• Frequency dividing circuits
• Time delay circuits
• Control counters

Counter Dividers Procurement Notes

Verify the specific suffix 'MT' against the official Texas Instruments datasheet to confirm package type and temperature grade. Ensure compatibility with system voltage levels, as HC series inputs require CMOS logic levels. Check for RoHS compliance status in the latest product change notification before procurement.

Counter Dividers Selection Notes

Select this component for applications requiring a 14-bit binary count sequence with buffered outputs. Consider the HC series for low power dissipation and wide supply voltage flexibility compared to HCT variants. Verify that the operating temperature range meets the environmental requirements of the target application.

Counter Dividers Part Context

This part belongs to the CDx4HC4020 family of high-speed CMOS logic devices. It is functionally similar to other 14-stage binary counters like the CD74HC4040 but offers additional output buffering. The device is designed for general-purpose digital counting applications in industrial and consumer electronics.

Counter Dividers Replacement Considerations

Compatible substitutes include SN74HC4020 variants from Texas Instruments or equivalent 14-stage binary counters from other manufacturers such as NXP Semiconductors, provided pinouts and electrical characteristics match.
