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

TDEC3–TDEC0. The drivers can be put into tri-

state mode by writing 0000 to the driver decode

switch. The receivers are controlled with data

bits RDEC3–RDEC0; 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.
