3.3 V 32-bit bus transceiver; 3-state
[1]
All typical values are at VCC = 3.3 V and Tamb = 25 °C unless otherwise specied.
[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 CC = 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 specied voltage level other than VCC or GND.
