CD4060BM/CD4060BC
14-Stage Ripple Carry Binary Counters
General Description
The CD4020BM/CD4020BC, CD4060BM/CD4060BC are
14-stage ripple carry binary counters, and the CD4040BM/
CD4040BC is a 12-stage ripple carry binary counter. The
counters are advanced one count on the negative transition
of each clock pulse. The counters are reset to the zero state
by a logical ‘‘1’’ at the reset input independent of clock.
Features
YWide supply voltage range 1.0V to 15V

YLow power TTL Fan out of 2 driving 74L
compatibility or 1 driving 74LS
YMedium speed operation 8 MHz typ. at VDD e10V
YSchmitt trigger clock input
