Device identity and functional role
The HEF4040BT,652 is a 14-stage binary counter from Nexperia's HEF4000 CMOS logic family, designed to increment on each negative-going clock edge and provide a ripple-carry output for cascading. It ships in a Bulk package — the loose-tube format suits low-to-medium volume assembly or prototyping where reeled tape-and-reel is not required.
