Low-power dual Schmitt trigger
[1] For measuring enable and disable times R
L
= 5 k, for measuring propagation delays, setup and hold times and pulse width R
L
= 1 M.
13. Transfer characteristics
Test data is given in Table 10.
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 the output impedance Z
o
of the pulse generator.
V
EXT
= External voltage for measuring switching times.
