Nexperia HEF4040BT,653 12-stage Surface Mount Binary Counter CMOS, 16-Pin SO16

The Nexperia 12-stage binary ripple counter is equipped with a clock input (CP), an asynchronous master reset input (MR), and twelve fully buffered outputs (Q0 to Q11). The counter advances on the high-to-low transition of the clock input, providing reliable binary counting functionality.

CMOS low power dissipation
High noise immunity
Tolerant of slow clock rise and fall time
Fully static operation
