WebExplanation: To interface TTL to CMOS a pull-up resistor must be used between the TTL output-CMOS input node and Vcc. A pull-up resistor is used to avoid the floating state on the input node of the CMOS, thus using a small amount of current. The value of RP will depend on the number of CMOS gates connected to the node. WebThe output drive current is an extremely important parameter in the field of digital electronics. It describes the amount of current that a single pin of an integrated circuit (IC) …
