HARA TERISTICS (Note 2)

The q denotes specifications which apply over the full operating

temperature range (0

°C ≤ TA ≤ 70°C for commercial grade).

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.

Note 3: Supply current is measured as the average over several charge

pump cycles. C + = C – = 0.1

µF, C1 = C2 = 0.2µF. All outputs are open with

all driver inputs tied high.

Note 4: Supply current and leakage 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.
