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:
adding a fixed voltage-divider bias resistive network at the output of the TTL device
avoiding this condition and only using TTL to drive TTL
adding an external pull-down resistor to ground
adding an external pull-up resistor to VCC
