FEATURES...
The
SP3488
and the
SP3489
are +3.3V low
power quad line receivers that meet the
specifications of the RS-485 and RS-422 serial
protocols. These devices are pin-to-pin
compatible with Sipex's SP488 and SP489
devices as well as popular industry standards.
The
SP3488
and
SP3489
devices feature
Sipex's BiCMOS process allowing low power
operation without sacrificing performance.
The RS-485 standard is ideal for multi-drop
applications or for long distance interfaces.
RS-485 allows up to 32 drivers and 32 receivers
to be connected to a data bus, making it an ideal
choice for multi-drop applications. Since the
