Web1 Apr 2004 · Signal Latchup deals with a SCR; however, the behavior is different from standard latchup in that the current monitored is from the I/O signal pad. During Signal Latchup, the anode is connected to the signal pin, whereas during standard latchup the anode is connected to the power supply; therefore, an additional latchup effect is possible … Web1 Jan 2011 · Heavy ion-induced single event latchup (SEL) is characterized in a commercially available CMOS readout integrated circuit operating at cryogenic temperatures.

Web22 Jan 2009 · Strictly speaking, latch-up is a process of firing up a parasitic thyristor formed by juctions n+/substaret/nwell/p+. In a commonly used layout slang, latch-up is a substrate or nwell tie used to prevent the firing up of the parasitic thyristor. This tie prevents the junctions to become forward biased.
