AC TEST CIRCUIT
AC TEST CONDITIONS
NOTES:
VZ is programmable from -2V to +7V.
IOL & I OH programmable from 0 to 16mA.
Tester Impedance Z
0
= 75 .
VZ is typically the midpoint of V
OH
and V
OL
.
IOL & IOH
are adjusted to simulate a typical resistive load circuit.
ATE tester includes jig capacitance.
