(1)

All devices receive a 1s test. Failure criterion is

≥ 5 PULSES OF ≥5 Pc.

(2)

The voltage rate-of-change across the isolation barrier that can be sustained without data errors.

(3)

Logic inputs are HCT-type and thresholds are a function of power-supply voltage with approximately 0.4 V hysteresis – see text.

(4)

Supply current measured with both transceivers set for the indicated mode. Supply current varies with data rate – see typical

characteristics.

(5)

Calculated from the maximum pulse width distortion (PWD), where Data Rate = 0.3/PWD.

(6)

Propagation time measured from VIN = 1.5 V to VO = 2.5 V.

(7)

The difference in propagation time of channel A and channel B in any combination of transmission directions.

(8)

The difference between propagation time of a rising edge and a falling edge.

(9)

When the device is powered up or direction is changed, the transceiver output is indeterminate (either high or low) and cannot be known

until an input signal is applied. The output begins to track the input as soon as the input receives a change in logic state, either low to

high or high to low.
