Unless otherwise specified: VDD = 13.2V; EN = VDD; PVCC = 5.5V; CPVCC = 2.2µF; CAVCC =2.2µF; CBOOT = 100nF to PHS;

PHS = PGND = 0V; TA= 25°C. UG is defined as UGH = UGL. LG is defined as LGH = LGL. Boldface specifications apply across

the operating temperature range from -55°C to +125°C and across a total ionizing dose of 75krad(Si) at +25°C with exposure

at a low dose rate of <10mrad(Si)/s. (Cont.)
