DRIVER DISABLE Threshold
Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: Testing done at VCC = 5V and VON/OFF = 3V.
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: VL supply current is measured with all receiver outputs low.
Note 5: Measurements in shutdown are performed with VON/OFF ≤ 0.1V.
Supply current measurements using driver disable are performed with
VDRIVER DISABLE ≥ 3V.
Note 6: 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 7: 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 8: Data rate operation guaranteed by slew rate, short-circuit current
and propagation delay tests.
ELECTRICAL CHARACTERISTICS The l denotes the specications which apply over the full operating
temperature range (0°C ≤ TA ≤ 70°C for commercial grade).
