Transcription

1 LOW POWER SUPER SMALL-SIZED SINGLE C-MOS COMPARATOR GENERAL DESCRIPTION The NJU79 is super small-sized package single C-MOS comparator with open drain output. The operating voltage is from.8v to.v. The output can drive TTL, C-MOS and various voltage levels. The input offset voltage is lower than 7mV and the package is super small-sized SC88A. The NJU79 is suitable for battery use items and other portable items.

V Power Dissipation P D (Note3) mw Operating Temperature Topr -4~+8 C Storage Temperature Tstg -~+ C Note) If the supply voltage (V DD ) is less than 7.V, the input voltage must not exceed the V DD level though 7.V is limit specified. Note) The output pull-up voltage must not over the V DD level. Note3) The power dissipation is value mounted on a glass epoxy board (FR-4) in size of xx.6 millimeters square. Note4) Decoupling capacitor should be connected between V DD and V SS due to the stabilized operation for the circuit.
