µP Reset Circuits with Long Manual Reset
Setup Period
Note: The first “_ _ ” is a placeholder for the threshold voltage
level of the devices. A desired threshold level is set by the two-
number suffix found in Table 1. The third "_" is a placeholder
for the manual reset setup period of the devices. A desired
setup period is set by the letter suffix found in Table 2. All
devices are available in tape-and-reel only. There is a 2500-
piece minimum order increment for standard versions (Table
2). Sample stock is typically held on standard versions only.
Nonstandard versions require a minimum order increment of
10,000 pieces. Contact factory for availability.
Devices are available in both leaded and lead-free packaging.
Specify lead-free by replacing “-T” with “+T” when ordering.
