Table 4. Capacitance
(TA = 25 °C)
Note: 1. Effective capacitance measured with power supply at 5V.
2. Sampled only, not 100% tested.
3. Outputs deselected.
Table 5. DC Characteristics
(TA = 0 to 70 °C or –40 to 85 °C; VCC = 4.75V to 5.5V or 4.5V to 5.5V)
Note: 1. Outputs deselected.
2. Negative spikes of –1V allowed for up to 10ns once per cycle.
Table 6. Power Down/Up Trip Points DC Characteristics (1)
(TA = 0 to 70 °C or –40 to 85 °C)
Note: 1. All voltages referenced to VSS.
2. CAPHAT and M4T32-BR12SH1 SNAPHAT only, M4T28-BR12SH1 SNAPHAT top tDR = 7 years (typ).
3. Using larger M4T32-BR12SH6 SNAPHAT top (recommended for Industrial Temperature Range - grade 6 device).
