NOTES:

1. All voltages are referenced to ground.

2. Logic 0 voltages are specified at a sink current of 4 mA at VCC=5V and 1.5 mA at VCC=2.0V,

VOL=GND for capacitive loads.

3. ICC1T and ICC2T are specified with CE set to a logic 0.

4. ICC1A and ICC2A are specified with CE= VCC, SCLK=2 MHz (0-VCC) at VCC=5V; SCLK=500 kHz

(0-VCC) at VCC=2.0V.

5. Measured at VIH=2.0V or VIL=0.8V and 10 ms maximum rise and fall time.

6. Measured with 50 pF load.

7. Measured at VOH=2.4V or VOL=0.4V.

8. VCC=VCC1, when VCC1>VCC2+0.2V (typical); VCC=VCC2, when VCC2>VCC1.

9. VCC2=0V.

10. VCC1=0V.

11. VCC1<VBAT.

12. Logic 1 voltages are specified at a source current of 1 mA at VCC=5V and 0.4 mA at 2.0V,

VOH=VCC for capacitive loads.

13. VCCIF must be less than or equal to the largest of VCC1, VCC2, and VBAT.
