SUPPLY VOLTAGE (V)
DIFFERENTIAL THRESHOLD VOLTAGE (mV)
Note 1: Current into a pin is defined as positive. Current out of a pin is defined as negative. All voltages are referenced to ground
except V
TH
, V
TL
, and V
ID
.
Note 2: Short only one output at a time. Do not exceed the absolute maximum junction temperature specification.
Note 3: AC parameters are guaranteed by design and characterization.
Note 4: C
L
includes scope probe and test jig capacitance.
Note 5: t
SKD1
is the magnitude difference of differential propagation delays in a channel. t
SKD1
= |t

Note 6: t
SKD2
is the magnitude difference of the t
PLHD
or t
PHLD
of one channel and the t
PLHD
or t
PHLD
of any other channel on the same part.
Note 7: t
SKD3
is the magnitude difference of any differential propagation delays between parts operating over rated conditions at
the same V
CC
and within 5°C of each other.
Note 8: t
SKD4
is the magnitude difference of any differential propagation delays between parts operating over rated conditions.
