Interface
► RS-232
Intersil offers a broad portfolio of robust, wide operating voltage range, RS-232 transceivers. There are many
transmitter and receiver combinations in standard inline packages plus space saving QFN package options as well.
Most operate over a wide 2.7V to 5.5V supply range with a variety of power down modes.
