AC CHARACTERISTICS FOR G4T AND H2 PACKAGES – WRITE/ERASE/PROGRAM OPERATIONS,CS CONTROLLED
(VCC = 5.0V, GND = 0V, TA = -55°C TO +100°C) (Note 6)
FIG. 4 AC TEST CIRCUIT
AC TEST CONDITIONS
Notes:
VZ is programmable from -2V to +7V.
IOL & IOH programmable from 0 to 16mA.
Tester Impedance Z0 = 75W.
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.
