The 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
• D. adding an external pull-up resistor to
• E. <i>V_CC</i>
