PMOS and CMOS have normally different supply requirements.
However, both can be operated from the same power supply provided it should be up to the CMOS limitation (15 V).
CMOS output can drive directly PMOS inputs, but not PMOS’s output to CMOS’s input.
How do you interface PMOS to CMOS?
A. By providing a pull-down resistor at the interconnection (PMOS output to CMOS input)
B. By providing a pull-up resistor at the interface
C. By inserting a series limiting resistor between PMOS output and CMOS input
D. By interfacing through an open-collector transistor configuration
