Quad Comparator
(276-1712)                 Specifications             Faxback Doc. # 31971

The 276-1712 consists of four independent voltage comparators which are
designed specifically to operate from a single power supply, compatibility
with all forms of logic,and power drain suitable for battery operation.
Among the applications are limit comparators; pulse, square-wave and time
delay generators; MOS clock timers; multivibrators and high voltage digital
logic gates.
