4.7.3

Electrical characteristics - 3.3 V supply

Typical values are given at TA = 25 °C, VDD1 = VDD2 = 3.3V. Minimum/maximum specifications apply over the entire

recommended operation range of VDD1 = VDD2 = 3.3 V ± 10%, and -40°C ≤ TA ≤ +125°C, unless otherwise noted.

Switching characteristics are tested with CLOAD = 15 pF and 50% duty cycle input square wave, over operating

range unless otherwise specified. Supply current values are calculated considering all channels are switching at

the same data rate. Parameters are tested in production unless otherwise specified. Only DC supply currents

are tested in production and the AC supply currents are not tested in production.
