The V_OH(min) rating of a TTL Gate Is Lower Than

Multiple Choice

The V_OH(min) rating of a TTL gate is lower than the V_IH(min) rating of a CMOS gate. Which of the following is commonly used to overcome this problem?

A) Adding a fixed voltage divider bias resistive network at the output of the TTL device
B) Adding an external pull- up resistor to V_cc
C) Adding an external pull- down resistor to ground
D) Avoiding this condition and only using TTL to drive TTL
