SP3494

SP3494 +3.3V Low Power RS-485/RS-422 Transceiver Operates From A Single +3.3V Supply Interoperable With +5.0V Logic +/-200mV Receiver Input Sensitivity -7V to +12V Common-Mode Input Voltage Range Allows Up To 32 transceivers On The Serial Bus Driver/Receiver Enable Lines 10µA Low-Power Shutdown Mode Compatibility with the MAX3486 and 75176 Industry Standard Pinout DESCRIPTION The SP3494 device is a +3.3V low power half-duplex transceiver that meets the specifications of the RS-485 and RS-422 serial protocols. This device is pin-to-pin compatible with the Exar SP3481 device as well as other popular industry standards. The SP3494 features the Exar BiCMOS process, allowing low power operation without sacrificing performance. The partially slew-rate limited drivers minimize EMI and reduce reflections caused by improperly terminated cables allowing error-free data transmission.The SP3494 is a half-duplex partially slew-rate limited transceiver that will del...
