dEScriPtion

The SP1490E is a low power differential line driver/receiver meeting RS-485 and RS-422 standards

up to 20Mbps. The SP1491E is identical to the SP1490E with the addition of driver and receiver tri-

state enable lines. Both products feature ±200mV receiver input sensitivity, over wide common mode

range. The SP1490E is available in an 8-pin NSOIC packages for operation over the commercial and

industrial temperature ranges. The SP1491E is available in a 14-pin NSOIC packages for operation

over the commercial and industrial temperature ranges.
