DC and AC parameters
Table 6.
1. Valid for ambient operating temperature: T
2. Typical value is at 25 °C and V
3. For devices with V
4. Guaranteed by design.
5. Input glitch immunity is equal to t
6. If left open, for improved system glitch immunity it is strongly recommended to connect a 0.1 µF decoupling ceramic
