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 8-pin plastic DIP and 8-pin

NSOIC packages for operation over the commercial and industrial temperature ranges. The

SP1491E

is available in 14-pin DIP and 14-pin NSOIC packages for operation over the

commercial and industrial temperature ranges.
