[1] Devices are designed to meet the DC specifications shown in this table, after thermal equilibrium has been established. The circuit is in
a test socket or mounted on a printed circuit board and transverse air flow greater than 500 LFPM is maintained.
[2] Input and output parameters vary 1:1 with V
CC
. V
EE
can vary ±0.3 V.
[3] Outputs are terminated through a 50 Ω resistor to V
CC
− 2V.
[4] V
IHCMR(min)
varies 1:1 with V
EE
, V
IHCMR(max)
varies 1:1 with V
CC
. The V
IHCMR
range is referenced to the most positive side of the
differential input signal. Normal operation is obtained if the HIGH level falls within the specified range and the peak-to-peak voltage lies
between V
p-p(min)
and 1 V.
