ADVANCE INFORMATION for pre-production products; subject to change without notice.
These devices are immune to quick voltage transient or excursion on VDD. Sensitivity to transients depends on both transient duration 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 and TLV809E devices have built-in glitch immunity as shown in Figure 25. When VDD falls below VIT-, RESET transitions low to indicate a fault condition after the propagation delay high-to-low (tPDHL). When VDD rises above VIT+, RESET only transitions to logic high indicating no more fault condition only if VDD remains above VIT+ for longer than the reset delay (tD).
