Valid for ambient operating temperature: TA = –40 to 85 °C; VCC = 1.6 V to 5.5 V (except where noted).

Typical values are at TA = +25 °C.

This blanking time allows the processor to start up correctly (see Figure 7, 8, 9, 10, 11, 12).

The internal pull-up resistor connected to the SR input is optional (see Table 10 for detailed device options).

Valid for push-pull only.

Minimal delay between enable off and enable on allows the application to power down properly. PB is ignored during this

period.
