SP1490E 20Mbps Full-Duplex RS-485 Transceivers with +/-15KV ESD

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
