The CD4026B IC's are each consist of a 5-stage Johnson decade counter and an output decoder which converts the Johnson code to a 7-segment decoded output for driving one stage in a numerical display. These devices are particularly advantageous in display applications where power dissipation low and /or low package count are important.

Features of CD4026 Decade Counters/Dividers:

• Counter and 7-segment decoding in one package.
• Easily interfaced with 7-segment display types.
• Fully static counter operation: DC to 6 MHz (typ.) at VDD = 10 V.
• Ideal for low-power displays.
• Display enable output (CD4026B).
• "Ripple blanking" and lamp test (CD4033B).
• 100% tested for quiescent current at 20 V.
• Standardized, symmetrical output characteristics.
• 5-V, 10-V, and 15-V parametric ratings.
• Schmitt-triggered clock inputs.

Applications of CD4026 Decade Counters/Dividers:

• Decade counting 7-segment decimal display.
• Frequency division 7-segment decimal displays.
• Clocks, watches, timers (e.g. ÷60, ÷60, ÷ 12 counter/display).
• Counter/display driver for meter applications.
