The White 68 lead CQFP fills
the same fit and function as
the JEDEC 68 lead CQFJ or 68
PLCC. But it has the TCE and
lead inspection advantage of
the CQFP form.

Notes:
VZ is programmable from -2V to +7V.
IOL & IOH programmable from 0 to 16mA.
Tester Impedance Z0 = 75 ½.
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.
