Table 6. DC Characteristics

Note: 1. Valid for Ambient Operating Temperature: TA = 0 to 70°C or –40 to 85°C; VCC = 2.7 to 3.6V or 4.5 to 5.5V(except where noted).

2. Outputs deselected.

3. For RST & BL pins (Open Drain).

4. Chip Enable outputs (E1CON - E4CON) can only sustain CMOS leakage currents in the battery back-up mode.

Higher leakage currents will reduce battery life.

5. Measured with VOUT and E1CON - E4CON open.
