It has an "on" resistance and an "off" resistance just like a relay contact or solid-state-relay.
WebThe 8085 provides IO/M signal to indicate whether the initiated cycle is for I/O device or for memory device. Using IO/M signal along with RD and WR, it is possible to generate … WebThe main use of tri-state gates is in driving logic lines or the connectors in a data bus (a contraction of the older term ‘bus-bar’ meaning a conductor providing a voltage or current, often from a power source, to many other devices). For example, in the connection of a microprocessor to RAM chips, it is necessary at some time that the microprocessor sends …
