Note: 1. The ASM2I99447 is capable of driving 50

Ω transmission lines on the incident edge. Each output drives one 50Ω parallel terminated transmission line to

2. Inputs have pull-down or pull-up resistors affecting the input current.

3. ICCQ is the DC current consumption of the device with all outputs open and the input in its default state or open.
