3.3 V 16-bit bus transceiver/register; 3-state
[1] All typical values are measured at V

= 3.3 V and T

= 25 °C.
[2] For valid test results, data must not be loaded into the flip-flops (or latches) after applying power.

or GND.
[4] This is the bus-hold overdrive current required to force the input to the opposite logic state.
[5] This parameter is valid for any V
CC

CC
=1.2VtoV
CC

a transition time of 100 µs is permitted. This parameter is valid for T
amb
= 25 °C only.
[6] I
CC
is measured with 16 outputs LOW.
[7] I
CC
is measured with outputs pulled to V
CC
or GND.
[8] This is the increase in supply current for each input at the specified voltage level other than V
CC
or GND.
