CD4026 belongs to the 4000 Series CMOS Logic Family of Integrated Circuits (IC’s) constructed with N- and P-channel enhancement mode transistors. CD4026 has Decade Counters/Dividers
CD4026 has a supply voltage range of 5V to 20V, which is much higher than any contemporary logic family. It has buffered output which improves transfer characteristics by providing very high gain. All inputs are protected against static discharge with diodes to VDD and VSS.
CD4026 Features
- 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 (CD40268)
- “Ripple blanking” and lamp test (CD4033B)
- 100% tested for quiescent current at 20V
- Standardized, symmetrical output characteristics
- 5-V, 10-V, and 15-V parametric ratings
- Schmitt-triggered clock inputs
