Recommended DC Operating Conditions
1. TA = -40°C to +85°C, otherwise specified.
2. Overshoot: VCC+1.0V in case of pulse width less than or equal to 20ns.
3. Undershoot: -1.0V in case of pulse width less than or equal to 20ns.
4. Overshoot and undershoot are sampled, not 100% tested.
Capacitance (f = 1MHz, TA = +25°C) (Note 1)
1. Capacitance is sampled, not 100% tested.
DC and Operating Characteristics
1. Typical values are tested at VCC=2.9V, TA=25°C and not guaranteed.
2. Standby mode is supposed to be set up after at least one active operation.
ISB1 is measured after 60ms from the time when standby mode is set up.
AC Operating Conditions
Test Conditions (Test Load and Test Input/Output Reference)
Input pulse level: 0.4 to 2.2V
