ELECTRICAL SPECIFICATIONS Absolute Maximum Ratings (TA = +25 °C) Parameter Symbol Test Conditions Rating Unit Power supply voltage VDD –0.3 to +3.8 V Input voltage VI KI/O, KI, S0, S1, S2 –0.3 to VDD + 0.3 V Output voltage VO –0.3 to VDD + 0.3 V High-level output current IOHNote REM Peak value –30 mA rms –20 mA LED Peak value –7.5 mA rms –5 mA One KI/O pin Peak value –13.5 mA rms –9 mA Total of LED and KI/O pins Peak value –18 mA rms –12 mA Low-level output current IOLNote REM Peak value 7.5 mA rms 5 mA LED Peak value 7.5 mA rms 5 mA Operating ambient TA –40 to +85 °C temperature Storage temperature Tstg –65 to +150 °C Note Work out the rms with: [rms] = [Peak value] × Duty. Caution Product quality may suffer if the absolute rating is exceeded for any parameter, even momen- tarily. In other words, an absolute maxumum rating is a value at which the possibility of psysical damage to the product cannnot be ruled out. Care must therefore be taken to ensure that the these ratings are not exceeded during use of the product.
