HA17901, HA17339 Series
Quadruple Comparators
Description
The HA17901 and HA17339 series products are comparators designed for use in power or control systems.
These IC operate from a single power-supply voltage over a wide range of voltages, and feature a reduced
power-supply current since the power-supply voltage is determined independently.
These comparators have the unique characteristic of ground being included in the common-mode input
voltage range, even when operating from a single-voltage power supply. These products have a wide range
of applications, including limit comparators, simple A/D converters, pulse/square-wave/time delay
generators, wide range VCO circuits, MOS clock timers, multivibrators, and high-voltage logic gates.
