16-bit dual supply translating transceiver; 3-state
9. Static characteristics
[1] V
CCO
is the supply voltage associated with the output port.
[2] V
CCI
is the supply voltage associated with the data input port.
[3] The bus hold circuit can sink at least the minimum low sustaining current at V
IL
max. I
BHL
should be measured after lowering V
I
to GND
and then raising it to V
IL
max.
[4] The bus hold circuit can source at least the minimum high sustaining current at V
IH
min. I
BHH
should be measured after raising V
I
to V
CC
and then lowering it to V
IH
min.
[5] An external driver must source at least I
BHLO
to switch this node from LOW to HIGH.
[6] An external driver must sink at least I
BHHO
to switch this node from HIGH to LOW.
[7] For I/O ports, the parameter I
OZ
includes the input leakage current.
