Note 1: Absolute Maximum Ratings are those values beyond which the life
of the device may be impaired.
Note 2: Testing done at VCC = 5V and VON/OFF = 3V, unless otherwise
specified.
Note 3: Supply current is measured as the average over several charge
pump burst cycles. C+ = 1.0µF, C – = 0.1µF, C1 = C2 = 0.2µF. All outputs
are open, with all driver inputs tied high.
Note 4: Measurements in shutdown are performed with VON/OFF ≤ 0.1V.
Supply current measurements using driver disable are performed with
VDRIVER DISABLE ≥ 3V.
Note 5: For driver delay measurements, RL = 3k and CL = 51pF. Trigger
points are set between the driver’s input logic threshold and the output
transition to the zero crossing (tHL = 1.4V to 0V and tLH = 1.4V to 0V).
Note 6: For receiver delay measurements, CL = 51pF. Trigger points are
set between the receiver’s input logic threshold and the output transition
to standard TTL/CMOS logic threshold (tHL = 1.3V to 2.4V and tLH = 1.7V
to 0.8V).
Note 7: Data rate operation guaranteed by slew rate, short-circuit current
and propagation delay tests.
