Dual bus switch with level shifting
13. Test information
Test data is given in
All input pulses are supplied by generators having the following characteristics: PRR
≤ 10 MHz; Z
o
= 50
Ω.
The outputs are measured one at a time with one transition per measurement.
Definitions for test circuit:
R
L
= Load resistance.
C
L
= Load capacitance including jig and probe capacitance.
R
T
= Termination resistance should be equal to output impedance Z
o
of the pulse generator.
V
EXT
= External voltage for measuring switching times.
