3.3 V octal transceiver with direction pin (3-state)
[1] All typical values are measured at V

[3] 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
= 1.2 V to V
CC
=3.3V 0.3 V
a transition time of 100 ms is permitted. This parameter is valid for T
amb
= +25 C only.
[4] This is the bus hold overdrive current required to force the input to the opposite logic state.
[5] This is the increase in supply current for each input at the specified voltage level other than V
CC
or GND.
