CD4520BF3A Description

The CD4520BF3A from Texas Instruments is a dual 4-bit binary counter belonging to the 4000B series, designed for high-reliability digital counting applications. Housed in a 16-pin CDIP package, it operates over a wide voltage range (3V to 18V), making it versatile for both low-power and industrial systems. This synchronous counter features two independent 4-bit counters, each capable of counting up at a maximum rate of 8 MHz. Its asynchronous reset and dual-edge triggering (positive/negative) provide flexible control, while its ROHS3 compliance ensures environmental safety.
