Table 1. (Continued)

² The minimum pulse width is the shortest pulse width at which the specified pulse width distortion is guaranteed.

³ The maximum data rate is the fastest data rate at which the specified pulse width distortion is guaranteed.

4 tPHL propagation delay is measured from the 50% level of the falling edge of the VIx signal to the 50% level of the falling edge of the VOx signal. tPLH propagation delay is measured from the 50% level of the rising edge of the VIx signal to the 50% level of the rising edge of the VOx signal.

5 tPSK is the magnitude of the worst-case difference in tPHL and/or tPLH that is measured between units at the same operating temperature, supply voltages, and output load within the recommended operating conditions.

⁶ Codirectional channel-to-channel matching is the absolute value of the difference in propagation delays between any two channels with inputs on the same side of the isolation barrier. Opposing directional channel-to-channel matching is the absolute value of the difference in propagation delays between any two channels with inputs on opposing sides of the isolation barrier.

• ⁷ CM^H is the maximum common-mode voltage slew rate that can be sustained while maintaining V^O > 0.8 VDD2. CM^L is the maximum common-mode voltage slew rate that can be sustained while maintaining V^O < 0.8 V. The common-mode voltage slew rates apply to both rising and falling common-mode voltage edges. The transient magnitude is the range over which the common mode is slewed.
• ⁸ Dynamic supply current is the incremental amount of supply current required for a 1 Mbps increase in the signal data rate. See Figure 6 through Figure 8 for information on per-channel supply current as a function of data rate for unloaded and loaded conditions. See the Power Consumption section for guidance on calculating per-channel supply current for a given data rate.

Ambient temperature = 25°C, unless otherwise noted.

MAXIMUM CONTINUOUS WORKING VOLTAGE

Table 14. Maximum Continuous Working Voltage¹

• ⁵ See Figure 3 for maximum rated current values for various temperatures.
• ⁶ Refers to common-mode transients across the insulation barrier. Commonmode transients exceeding the absolute maximum ratings can cause latch-up or permanent damage.

Stresses at or above those listed under Absolute Maximum Ratings may cause permanent damage to the product. This is a stress rating only; functional operation of the product at these or any other conditions above those indicated in the operational section of this specification is not implied. Operation beyond the maximum operating conditions for extended periods may affect product reliability.

ESD CAUTION

ESD (electrostatic discharge) sensitive device. Charged devices and circuit boards can discharge without detection. Although this product features patented or proprietary protection circuitry, damage may occur on devices subjected to high energy ESD. Therefore, proper ESD precautions should be taken to avoid performance degradation or loss of functionality.
