Note 1:
Absolute Maximum Ratings are those values beyond which the life
of the device may be impaired.
Note 2:
Testing done at V
CC
= 5V and V
ON/OFF
= 3V.
Note 3:
Supply current is measured as the average over several charge
pump burst cycles. C

are open, with all driver inputs tied high.
Note 4:
V

supply current is measured with all receiver outputs low.
Note 5:
Measurements in shutdown are performed with V
ON/OFF
≤
0.1V.
Supply current measurements using driver disable are performed with
V
DRIVER DISABLE
≥
3V.
Note 6:
For driver delay measurements, R
L
= 3k and C
L
= 51pF. Trigger
points are set between the driver’s input logic threshold and the output
transition to the zero crossing (t
HL
= 1.4V to 0V and t
LH
= 1.4V to 0V).
Note 7:
For receiver delay measurements, C
L
= 51pF. Trigger points are
set between the receiver’s input logic threshold and the output transition
to standard TTL/CMOS logic threshold (t
HL
= 1.3V to 2.4V and t
LH
= 1.7V
to 0.8V).
Note 8:
Data rate operation guaranteed by slew rate, short-circuit current
and propagation delay tests.
