NOTES:

1) All voltages are referenced to ground.

2) Measured with outputs open and inputs at VCC or GND.

3) Measured with outputs open and VCC or VBAT < 2.7V.

4) Measured with outputs open and both VCC and VBAT < 5.5V.

5) Measured with outputs open and both VCC and VBAT < 3.6V.

6) VOUT = VCC - 0.3V.

7) VOUT = VBAT - 0.3V.

8) VCC < 2.7V.

9) VBAT < 2.0V and VCC < 1.9V.

10) VCCFTP is offset by approximately 0.1V from VCCRTP.

11) VBAT in the off state and VBAT < VCC (VBAT > VCC and VBAT in the off state 1.5μA maximum).

12) tR = 5μs with one supply < 2.5V.
