ELECTRICAL CHARACTERISTICS
MC68HC11A8
A-2
TECHNICAL DATA
A
NOTES:
1. VOH specification for RESET and MODA is not applicable because they are open-drain pins. VOH specification
not applicable to ports C and D in wired-OR mode.
2. Refer to A/D specification for leakage current for port E.
3. EXTAL is driven with a square wave, and
tcyc = 500 ns for 2 MHz rating;
tcyc = 333 ns for 3 MHz rating.
VIL ≤ 0.2 V
VIH ≥ VDD – 0.2 V
No dc loads.
