Overview
The CD4026BEE4 is a CMOS decade counter/divider integrated circuit produced by Texas Instruments. It combines a 5-stage Johnson decade counter with an output decoder that converts the Johnson code to a 7-segment decoded output, suitable for driving one stage in a numerical display. This device is particularly advantageous in display applications where low power dissipation and/or low package count are important.
