AC TEST CIRCUIT
NOTES:
VZ is programmable from -2V to +7V.
IOL & IOH programmable from 0 to 16mA.
Tester Impedance Z0 = 75 Ω.
VZ is typically the midpoint of VOH and VOL.
IOL & IOH are adjusted to simulate a typical resistive load circuit.
ATE tester includes jig capacitance.

The WEDC 68 lead G2T CQFP
fills the same fit and function as
the JEDEC 68 lead CQFJ or 68
PLCC. But the G2T has the TCE
