Not tested in production. Note4: Guaranteed by Design but not tested in production. Note5: Upgrade to industrial/MSL2 level applies from date codes 1227 (marking explained on application note AN1132 page 2). Products with prior date code of 1227 are qualified with MSL3 for Consumer market. Electrical Specifications (continued) Unless otherwise specified, these specification apply over 4.5V< V cc<5.5V, Vin=12V, 0 oC<T j< 125 oC. Typical values are specified at T a = 25 oC. |
