18-bit universal bus transceiver; 3-state
[6] I
CC
is measured with outputs pulled up to V
CC
or pulled down to ground.
[7] This is the increase in supply current for each input at the specified voltage level other than V
CC
or GND.
[8] All typical values are at V
CC
= 3.3 V and T
amb
= 25 °C.
[9] This is the bus hold overdrive current required to force the input to the opposite logic state.
[10] This parameter is valid for any V
CC
between 0 V and 1.2 V with a transition time of up to 10 ms. From V
CC
=1.2VtoV
CC
= 3.3 V ± 0.3 V
a transition time of 100 µs is permitted. This parameter is valid for T
amb
=25°C only.
