AC CHARACTERISTICS (continued)
(V
CC
= +3.0V to +3.6V, R
L
= 100Ω ±1%, C
L
= 5pF, T
A
= -40°C to +85°C, unless otherwise noted. Typical values are at V
CC
= +3.3V,
T
A
= +25°C.) (Notes 3, 4, 5; Figures 2, 3)
Note 1: Maximum and minimum limits over temperature are guaranteed by design. Devices are production tested at T
A
= +25°C.
Note 2: By definition, current into the device is positive and current out of the device is negative. Voltages are referred to device
ground except V
OD
.
Note 3: AC parameters are guaranteed by design and characterization.
Note 4: C
L
includes probe and fixture capacitance.
Note 5: Signal generator conditions for dynamic tests: V
OL
= 0, V
OH
= 3V, f = 20MHz, 50% duty cycle, R
O
= 50Ω, t
R
1ns, and t
F
1ns (0 to 100%).
Note 6: t
SKD1
is the magnitude difference of differential propagation delays in a channel; t
SKD1
= | t
PHLD
- t
PLHD
|.
Note 7: t
SKD2
is the magnitude 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 device (MAX9112).
Note 8: t
SKD3
is the magnitude difference of any differential propagation delays between devices at the same V
CC
and within 5°C
of each other.
Note 9: t
SKD4
is the magnitude difference of any differential propagation delays between devices operating over the rated supply
and temperature ranges.
Note 10:f
