Notes
Test levels (DC and AC Characteristics)
level 1: production tested at 25° C and over full power supply range
level 2: production tested at 25° C and VEE = -5.0 V
level 3: guaranteed by design and characterization test over full temperature and power supply range
level 4: typical value only, not confirmed by test
level 5: guaranteed by design and characterization at 25 °C and VEE = -5.0 V

Logic threshold levels for inputs SCLK, SDATA and SDEN. Note that this is a negative-supply device
(VEE,VSS = -5 V, VCC, VDD = 0 V). It can be also used for positive-supply systems if the input
signals are referred to VCC, VDD = +5 V and VEE,VSS = 0 V.
