can operate up to 5Mbps. All of the differential
receivers can receive data up to 5Mbps.
Decoder
The
SP503
has the ability to change the inter-
face mode of the drivers or receivers via an 8–bit
switch. The decoder for the drivers and receiv-
ers is not latched; it is merely a combinational
logic switch. The codes shown in
Tables 1 and
2
are the only specified, valid modes for the
SP503
. Undefined codes may represent other
interface modes not specified or random outputs
(consult the factory for more information). The
drivers are controlled with the data bits labeled
TDEC
–TDEC
. The drivers can be put into tri-
state mode by writing 0000 to the driver decode
switch. The receivers are controlled with data
bits RDEC
–RDEC
; the code 0000 written to
the receivers will place the outputs in an unde-
termined state. All receivers, with the exception
of SCT, do not have tri-state capability; the
outputs will either be HIGH or LOWdepending
upon the state of the receiver input.
