ZEN2044F 33MHz Up/down Counter

The ZEN2044F is a 24bit x 4ch. programmable universal counter LSI. The ZEN2044F can count phase-shifted pulse signals or up/down pulse signals generated from rotary encoders or linear scales. Since the counter response speed is as high as 33MHz(MAX), the ZEN2044F can be used in a variety of applicat.
