PCF8566
10 DC CHARACTERISTICS
VSS =0V; VDD = 2.5 to 6 V; VLCD =VDD 2.5 to VDD 6 V; Tamb = 40 to +85 °C; unless otherwise specied.
Notes
1. Outputs open; inputs at VSS or VDD; external clock with 50% duty factor; I2C-bus inactive.
2. Resets all logic when VDD <Vref.
3. Periodically sampled, not 100% tested.
4. Outputs measured one at a time.
