DESCRIPTION

The SP507 is a monolithic IC that supports seven (7) popular serial interface standards for

DTE/DCE connectivity. The seven (7) drivers and seven (7) receivers transmit and receive

signals at over 20Mbps. The SP507 requires no additional external components for compliant

operation for all seven (7) modes of operation. All necessary termination is integrated within

the SP507 and is switchable when V.35 drivers, V.35 receivers, and V.11 receivers are used.

The SP507 can operate as either a DTE or DCE.

Additional features include a latch enable pin with the driver and receiver address decoder.

Tri-state ability for the driver and receiver outputs is controlled by supplying a 3-bit word into

the address decoder. Four (4) drivers and four (4) receivers in the SP507 include separate

enable pins for added convenience.
