4-channel I2C-bus multiplexer with interrupt logic

11. Static characteristics

[1]

For operation between published voltage ranges, refer to worst case parameter in both ranges.

[2]

In order to reset part, VDD must be lowered to 0.2 V for at least 5 s.

Table 8.

Static characteristics at VDD =2.3 V to 3.6V

VSS =0V; Tamb = 40 C to +85 C; unless otherwise specified. See Table 9 for VDD = 4.5 V to 5.5 V.[1]
