Notes: 1. All voltage referred to VSS.
2. The supply voltage with all VCC and VCCQ pins must be on the same level.
3. The supply voltage with all VSS and VSSQ pins must be on the same level.
4. VIH (max) = VCC + 2.0 V for pulse width ≤ 3 ns at VCC.
5. VIL (min) = VSS – 2.0 V for pulse width ≤ 3 ns at VSS.
