Overview

Product details

XD4518 Dual BCD Up Counter 4-stage counter. The counter stages are D-type flip-flops with interchangeable clock and enable lines for incrementing on either positive or negative going transitions. For single unit operation, the enable input is held high and the counter advances on every positive* going transition of the clock. The counter is cleared by a high on its reset line. The counters can be cascaded in ripplemode by connecting Q4 to the enable input.
