Q. he problem of the VOH(min) of a TTL IC being too low to drive a CMOS circuit and meet the CMOS requirement of VIH(min) is usually easily overcome by:
(A) adding a fixed voltage- divider bias resistive network at the output of the ttl device
(B) avoiding this condition and only using ttl to drive ttl
(C) adding an external pull- down resistor to ground
