11.12 Analog Comparator Characteristics

Operating conditions: VDD =5V, fosc = 0,TA =90

°C unless otherwise specified

(*) fosc = 1,5,10, 20 MHz , VDD = 5 V, VPBO = 2 V, Resolution = 8 bit, CS= 22nF, TA =25°C.

11.13 Triac Driver Characteristics

Operating conditions: VDD =5V, fosc = 0,TA =90

°C

Notes:

1. The IIO current sunk must always respects the absolute maximum rating specified in Section 11.2 and the sum of IIO

(I/O ports and control pins) must not exceed IVSS

2. The IIO sourced current must always respect the absolute maximum rating specified in Section 11.2 and the sum of IIO

(I/O ports and control pins) must not exceed IVDD.
