Notes: 1. All parameters are referred to VSS, when measured.
2. VCCQ must be lower than or equal to VCC.
3. VIH is allowed to exceed VCC up to 4.6V for the period shorter than or equal to 5ns.
4. VIL is allowed to outreach below VSS down to –1.0V for the period shorter than or equal to 5ns.
5. VIN (dc) specifies the allowable dc execution of each differential input.
6. VSWING (dc) specifies the input differential voltage required for switching.
