The devices feaurefully static operation requiring no external:Iocks or timing strobes, with equal address accesslnd cycle times. They require a single +5V ± 10lob supply, and are fully TTL compatible.rhe MK48H64 and MK48H65 have a Chip Enablelower down feature which sustains an automaticstandby mode whenever either Chip Enable goesoactive (E1 goes high or E2 goes lOw).
