Ordering number : ENA1419 LC79401KNE CMOS LSI LC79401KNE Specifications Absolute Maximum Ratings at Ta = 252C, V = 0V SS Parameter Symbol Conditions Ratings unit Maximum supply voltage (Logic) V max -0.3 to +7.0 V DD Maximum supply voltage (LCD) V -V max *1 0 to 35 V DD EE Maximum input voltage V max -0.3 to V +0.3 V I DD Storage temperature Tstg -40 to +125 C Note *1 V V1>V3>V4>V , V -V37V, V4-V 7V DD EE DD EE Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.
