Latchup Characterization From: May Lai To: G. Korsh, E. Hui, C. Lionbarger, L. Y. Lee Packaged units of AT27C040 (18710A Stepping) from lot 3C1660 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 in Table 1 indicate that the AT27C040 (18710A) is quite immune to latchup under normal operating conditions (Vcc = 5.0V, Room Temperature). All input pins can sustain more than -600mA and junction breakdown occurs at voltages greater than 23V. The only latchup occurence is observed for positive output voltages of 14.0V, requiring a current of 580mA. No latchup is observed for negative output voltages up to -2.0V & -600mA.
