All outputs are CMOS drive levels and can be used with CMOS or TTL logic.
I/O Pin Types
Input. High impedance, TTL.
Output. CMOS.
Input/Output. TTL input/CMOS output.
Three-state. Bidirectional three-state I/O pin.
Sustained three-state. This is an active-low, three-state signal owned by only one driver at a time. The driver that drives an
s/t/s signal low must drive it high for at least one clock cycle before allowing it to float. A pullup is required to sustain the
deaserted value.
Open drain.
