Ship Radar Endorsement: Element 8

1. A CMOS logic requires a supply voltage of 5 volts 20%, whereas TTL logic requires 5 volts 5%.
2. B Unused inputs should be tied high or low as necessary especially in the CMOS family.
3. C At higher operating frequencies, CMOS circuits consume almost as much power as TTL circuits.
4. D When a CMOS input is held low, it sources current into whatever it drives.
