Pearce To: Copy: G. Korsh, E. Hui, C. Lionbarger M. Wong, H. Nguyen, LY. Lee Three packaged units of the AT27C4096 (18709A Stepping) from lot 4D1705 were tested for latchup. A curve tracer was used to force current into each pin and observe the latchup trigger current and voltage. A 9 ohm resistor was connected in parallel across the Vcc power supply to allow current to be forced out of the Vcc pin during testing. A separate ammeter was connected in series with the Vcc power supply to verify when latchup occurred. The results are show in page 2 an indicate that the new AT27C4096 (18709A) is quite immune to latchup under normal operating conditions (Vcc=4.5v to 5.5v room temperature). Inputs can sustain -3.3v with respect to ground and no latchup is observed. No latchup is observed for possitive input voltages up to 18v where destructive junction breakdown occurs. Outputs can sustain 11.0v and -3.3v with respect to ground and no latchup is observed.
