Static characteristics
[1]
The PCK9446 is capable of driving 50
Ω transmission lines on the incident edge. Each output can drive one 50 Ω parallel terminated
transmission line to a termination voltage of VT. Alternately, the device drives up to two 50 Ω series terminated transmission lines.
[2]
Input pull-up/pull-down resistors influence input current.
