3.3 V octal D-type transparent latch; 3-state
[1] Typical values are measured at V

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

[6] I
CC
is measured with outputs pulled to V
CC
or GND.
[7] This is the increase in supply current for each input at the specified voltage level other than V
