Note 1: All voltages are measured with respect to the ground pin, unless otherwise specified.
Note 2: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is func-
tional, but do not guarantee specific performance limits. Electrical Characteristics state DC and AC electrical specifications under particular test conditions which guar-
antee specific performance limits. This assumes that the device is within the Operating Ratings. Specifications are not guaranteed for parameters where no limit is
given, however, the typical value is a good indication of device performance.
Note 3: For operating at elevated temperatures the device must be derated above 25˚C based on a +150˚C maximum junction temperature and a thermal resistance
170˚C/W (S0-8), junction to ambient.
Note 4: Supply current when output high typically 9mA and MAX. is 13mA at Vcc=15V.
.
Note 5: Tested at VCC = 5V and VCC = 15V.
Note 6: This will determine the maximum value of RA + RB for 15V operation. The maximum total (RA + RB) is 20MΩ.
Note 7: No protection against excessive pin 7 current is necessary providing the package dissipation rating will not be exceeded.
