Note 3:
Supply current is measured with driver and receiver outputs
unloaded and the driver inputs tied high.
Note 4:
Supply current and leakage current 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 5:
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 6:
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 7:
Absolute maximum externally applied voltage. Internal charge
pump may force a larger value on this pin.
