3.3 V 16-bit buffer/driver; 3-state
[1]
Typical values are measured at VCC = 3.3 V and at Tamb = 25 C.
[2]
Unused pins at VCC or GND.
[3]
This is the bus hold overdrive current required to force the input to the opposite logic state.
[4]
This parameter is valid for any VCC between 0 V and 1.2 V with a transition time of up to 10 ms. From VCC = 1.2 V to VCC = 3.3 V 0.3 V
a transition time of 100
s is permitted. This parameter is valid for T
amb = 25 C only.
[5]
ICC is measured with outputs pulled to VCC or GND.
[6]
This is the increase in supply current for each input at the specified voltage level other than VCC or GND.
