‡: Typical figure are at VDD = 5V and temperature = 25° C and are for design aid only, not guaranteed and not subject to

production testing.

Notes:

1: VOH = 0.9 VDRVDD.

2: VOL = 0.1 VDRVDD.

3. All digital input pin, CDSCK1, CDSCK2, ADCCLK and SCLK are exclusive.

4. CDSCK1, CDSCK2, ADCCLK and SCLK schmitt trigger input pins.
