3 DESCRIPTIONS

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, SOP8, MSOP8, SOP14 and TSSOP14

packages. It operates over an ambient temperature

range of -40°C to +125°C.
