TERMINOLOGY

IDD1 (Q)

IDD1(Q) is the minimum operating current drawn at the VDD1 pin

when there is no external load at VISO and the I/O pins are

operating below 2 Mbps, requiring no additional dynamic supply

current. IDD1(Q) reflects the minimum current operating condition.

IDD1 (D)

IDD1 (D) is the typical input supply current with all channels

simultaneously driven at a maximum data rate of 25 Mbps

with full capacitive load representing the maximum dynamic

load conditions. Resistive loads on the outputs should be

treated separately from the dynamic load.

IDD1 (MAX)

IDD1 (MAX) is the input current under full dynamic and VISO load

conditions.

tPHL Propagation Delay

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

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.

tPSK Propagation Delay Skew

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.

tPSKCD/tPSKOD Channel-to-Channel Matching

Channel-to-channel matching is the absolute value of the

difference in propagation delays between the two channels

when operated with identical loads.

Minimum Pulse Width

The minimum pulse width is the shortest pulse width at which

the specified pulse width distortion is guaranteed.

Maximum Data Rate

The maximum data rate is the fastest data rate at which the

specified pulse width distortion is guaranteed.
