DESCRIPTION
The RS331 and RS393 is the single and dual
comparator version, the RS339 is quad comparator
version, and both are open-drain output comparators for
maximum flexibility. It can operate from 1.8V to 5.5V,
and have low power consuming 50μA (TYP) per
channel.
The RS331, RS393 and RS339 are the most cost-
effective solutions for applications where low voltage
operation, low power and space saving are the primary
specifications in circuit design for portable consumer
products.
The RS331, RS393 and RS339 are available in Green
SOT23-5, SOIC-8, MSOP-8, SOIC-14 and TSSOP-14
packages. It operates over an ambient temperature
range of -40°C to +125°C.
