Description
CD4026 – Decade Counter / Divider with 7-Segment Decoder
The CD4026 is a CMOS decade counter and display driver designed to drive 7-segment LED displays directly. It counts from 0 to 9 (BCD format) and automatically decodes the binary count into a 7-segment output to display numeric digits. With features such as ripple blanking, carry-out, and clock inhibit, it is ideal for digital counting applications where direct LED display control is needed.
✅ Key Features:
-
Counts from 0 to 9 in binary-coded decimal (BCD)
-
7-segment display output (a–g) for direct driving of LEDs
-
Ripple blanking input/output (BI/RBO) and latch enable
-
Clock inhibit (CI) and reset (CLR) inputs
-
Carry-out (CO) for cascading counters
-
Wide supply voltage range: 3V to 15V
-
CMOS technology – low power and high noise immunity
