Note: The first “_ _” are placeholders for the threshold voltage

levels of the devices. Desired threshold levels are set by the part

number suffix found in the Reset Voltage Threshold Suffix Guide.

The “_” after the D is a placeholder for the reset timeout delay

time. Desired delay time is set using the timeout period suffix

found in the Reset Timeout Period Suffix Guide. For example the

Devices are available in both leaded and lead-free packaging.

Specify lead-free by replacing "-T" with "+T" when ordering.
