Note 1:
Maximum and minimum limits over temperature are guaranteed by design and characterization. Parts are production
tested at T
A
= +25
°
C.
Note 2:
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 3:
Short one output at a time.
Note 4:
AC parameters are guaranteed by design and characterization. Limits are set at ±6 sigma.
Note 5:

includes scope probe and test jig capacitance.
Note 6:
Pulse generator differential output for all tests (unless otherwise noted): t
R

F
< 1ns (0% to 100%), frequency = 100MHz,
50% duty cycle.
Note 7:
t

Note 8:
t
SKD2
is the magnitude of the difference of the t
PLHD
or t
PHLD
of one channel and the t
PLHD
or t
PHLD
of the other channel
on the same part.
Note 9:
t
SKD3
is the magnitude of the difference of any differential propagation delays between parts at the same V
CC
and within
5

C of each other.
Note 10:

is the magnitude of the difference of any differential propagation delays between parts operating over the rated
supply and temperature ranges.
