Question: What must be done to interface TTL to CMOS?
Options
A : A dropping resistor must be used on the CMOS 12 V supply to reduce it to 5 V for the TTL.
B : As long as the CMOS supply voltage is 5 V, they can be interfaced; however, the fan-out of the TTL is limited to five CMOS gates.
C : A 5 V Zener diode must be placed across the inputs of the TTL gates in order to protect them from the higher output voltages of the CMOS gates.
D : A pull-up resistor must be used between the TTL output-CMOS input node and V cc ; the value of RP will depend on the number of CMOS gates connected to the node.
