SP306CT
SP306CT is RS-422/RS-423 Line Drivers/Receivers manufactured by Sipex.
DESCRIPTION
… The SP306 is a single chip device that offers both RS-422 and RS-423- type serial interfaces. The device can be programmed to provide two full- duplex channels of either RS-422 or RS-423 via two mode control pins. The SP306 also features a loopback function that can be activated in any operating mode. The SP306 is available in a 28- pin SOIC package for operation over the mercial temperature range.
