Notes
a. Refer to PROCESS OPTION FLOWCHART for additional information.
b. Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.
c. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum.
d. To supply the output current of 10 mA on a dc basis, an external 13-V supply must be connected between the CAP pin and the S1 pin with the
e. For testing purposes, the 10-mA load current must be supplied by an external current source to the V
f. Internally generated voltage for reference only.
g. V
Notes
a. FAULT output retains previous state until ENABLE rising edge.
b. Latch FAULT condition, reset by ENABLE rising edge.
