Synchronous up/down counter, binary/decade counter

DESCRIPTION The HEF4029B is a synchronous edge-triggered up/down 4-bit binary/BCD decade counter with a clock input (CP), an active LOW count enable input (CE), an up/down control input (UP/DN), a binary/decade control input (BIN/DEC), an overriding asynchronous active HIGH parallel load input
