Power Consumption

This section details the power consumption of the device as measured during various modes of operation. Power dis-

sipation is determined by temperature, supply voltage, and external source/sink requirements.

Note:

Maximum values represent very short bursts of activity over a small amount of time. Typical values repre-

sent averaged current consumption over time.

DC Specifications

Note3:This specification applies to all inputs and tri-stated bi-directional pins. Internal pull-down and pull-up

resistors add +/- 50 µA per-pin (typical).
