LP265 Datasheet, PDF (5/10 Pages) National Semiconductor (TI) – Micropower Programmable Quad Comparator

Typical Applications
Gated 4-Phase Oscillator
‘‘Voting’’ Comparator

All four phases run when X is low When X is high oscillation stops and
power drain is zero
TL H 5023 – 5
If V_E e 0 25V then V_OUT will be low if 1 of the 3 other outputs are low
Choice of V_E e 0 50V causes V_OUT to be low if 2 of the 3 other outputs are
low V_E e 0 75V will cause V_OUT to be low if all 3 other outputs are low
