CD4026BEE4

Counter Dividers Overview

The CD4026BEE4 is a CMOS decade counter and divider manufactured by Texas Instruments. It features a five-stage Johnson decade counter with an output decoder that converts Johnson codes into seven-segment decoded outputs for driving digital displays. The device operates within a supply voltage range of 3 V to 18 V and supports input frequencies up to 16 MHz. It is housed in a 16-pin PDIP package and functions across an extended temperature range from -55 °C to +125 °C.

Counter Dividers Feature Summary

• Integrates a five-stage Johnson decade counter with built-in seven-segment decoding logic for direct display interfacing.
• Includes dedicated clock, reset, and clock inhibit inputs to control counting sequences and display states.
• Provides carry out and display enable outputs to facilitate cascading multiple counters or managing display activity.

Counter Dividers Applications

• Seven-segment LED or LCD numeric display systems
• Frequency division circuits
• Digital timing and clock generation modules

Counter Dividers Procurement Notes

Verify the component authenticity by checking the manufacturer marking against the official datasheet specifications. Ensure the ordering suffix matches the required package type and environmental compliance standards. Confirm the specific revision level if critical timing parameters are involved in the design. Cross-reference the pinout diagram with the target PCB footprint to prevent installation errors during assembly.

Counter Dividers Selection Notes

Select this component when a single-chip solution for decimal counting and direct seven-segment drive is required. It is suitable for designs needing low power consumption and wide voltage operation. Consider the 16 MHz maximum frequency limit for high-speed applications. Evaluate the need for additional external components if complex decoding beyond standard seven-segment formats is necessary.

Counter Dividers Part Context

This part belongs to the CD4000 series of CMOS logic integrated circuits produced by Texas Instruments. The series is known for its compatibility with various logic families and robust performance in consumer electronics. The E4 suffix typically indicates lead-free packaging compliant with RoHS directives, distinguishing it from older non-compliant variants within the same functional family.

Counter Dividers FAQ

What is the function of the Clock Inhibit input?

When the Clock Inhibit signal is high, the counter progression is disabled regardless of the clock signal state. If the clock line remains high, the Clock Inhibit signal can alternatively function as a negative-edge triggered clock.

How does the Reset input operate?

A high-level signal on the Reset input forces the decade counter to zero, clearing all internal stages immediately.
