Table 1. Pin Configuration
Note:1 VCCB is internally connected to VCC.
Table 2. Supported Single and Dual Supply Configurations
Note: 1 VCC is the positive power supply of the device core and input circuitry. VCC voltage defines the input threshold and levels
Table 3. Function Table (Controls)
Table 4. Absolute Maximum Ratings
Note: These are stress ratings only and are not implied for functional use. Exposure to absolute maximum ratings for prolonged periods of time may affect
device reliability.
