VZ = 1.5V
(Bipolar Supply)
AC CHARACTERISTICS – WRITE/ERASE/PROGRAM OPERATIONS,CS# CONTROLLED
VCC = 5.0V, VSS = 0V, VSS = 0V, -55°C ≤ TA ≤ +125°C
AC Test Conditions
FIGURE 2 – 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.
