Pearce To: G. Korsh, E. Hui, C. Lionbarger cc: M. Wong, LY. Lee Three packaged units of the AT27C512R (18704A Stepping) from lot 4B0511 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 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 and indicate that the new AT27C512R (18704A) is quite immune to latchup under normal operating conditions (Vcc=5.5V, room temperature). Inputs can sustain -3.5V with respect to ground and no latchup is observed. No latchup is observed for possitive input voltages up to 23V where destructive junction breakdown occurs. Outputs can sustain 11.4V and -2.5V with respect to ground and no latchup is observed.
