SP490E / SP491E
Enhanced Full-Duplex RS-485 Transceivers
Description
The SP490E is a low power differential line driver/receiver meeting
RS-485 and RS-422 standards up to 10Mbps. The SP491E is identical
to the SP490E with the addition of driver and receiver tri-state enable
lines. Both products feature ±200mV receiver input sensitivity, over
wide common mode range. The SP490E is available in 8-pin NSOIC
packages for operation over the commercial and industrial temperature
ranges. The SP491E is available in 14-pin NSOIC packages for
operation over the commercial and industrial temperature ranges.
