8-channel I2C-bus multiplexer with reset

10. Static characteristics

[1]

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

[2]

VDD must be lowered to 0.2 V in order to reset part.

Table 6.

Static characteristics

VDD = 2.3 V to 3.6 V; VSS = 0 V; Tamb = −40 °C to +85 °C; unless otherwise speciﬁed.

See Table 7 on page 15 for VDD = 4.5 V to 5.5 V.[1]
