Description
The 74LS290 is a two-sectioned high-speed 4-bit ripple type counter. Each counter contains a divide-by-two and a divide-by-five section, which are triggered by a High to Low transition on the clock inputs. The 74LS290 IC has a wide operating voltage range, and a wide operating temperature range. It directly interfaces with CMOS, NMOS, and TTL.
