These devices are immune to quick voltage transient or excursion on VDD. Sensitivity to transients depends on both pulse duration (tGI) found in Section 7.6 and transient overdrive. Overdrive is defined by how much VDD exceeds the specified threshold. Threshold overdrive is calculated as a percent of the threshold in question, as shown in Equation 1.
TLV803E, TLV809E, and TLV810E devices have
built-in glitch immunity (tGI) of 10 µs typical as shown in
Section 7.6. Figure 8-2 shows that VDD must fall below VIT- for tGI, otherwise the faling transistion is ignored. When VDD falls below VIT- for tGI, RESET transitions low to indicate a fault condition after the propagation delay high-to-low (tPDHL). When VDD rises above VIT+, RESET only deasserts to logic high indicating there is no more fault condition only if VDD remains above VIT+ for longer than the reset delay (tD).
