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.

ABSOLUTE MAXIMUM RATINGS
These are stress ratings only and functional operation of the device at these ratings or any other above those indicated in the operation sections of the specifications below is not implied. Exposure to absolute maximum rating conditions for extended periods of time may affect reliability. VCC............................................................................+7V Input Voltages: Logic...............................-0.3V to (VCC+0.5V) Drivers............................-0.3V to (VCC+0.5V) Receivers........................................15.5V Output Voltages: Logic................................-0.3V to (VCC+0.5V) Drivers................................................15V Receivers........................-0.3V to (VCC+0.5V) Storage Temperature..........................-65C to +150C Power Dissipation per package 80-pin QFP (derate 18.3mW/C above +70C)..1500mW
STORAGE CONSIDERATIONS
Due to the relatively large package size of the 80-pin quad flat-pack, storage in a low humidity environment is preferred. Large high density plastic packages are moisture sensitive and should be stored in Dry Vapor Barrier Bags. Prior to usage, the parts should remain bagged and stored below 40C and 60%RH. If the parts are removed from the bag, they should be used within 48 hours or stored in an environment at or below 20%RH. If the above conditions cannot be followed, the parts should be baked for four hours at 125C in order remove moisture prior to soldering. Exar ships the 80pin LQFP in Dry Vapor Barrier Bags with a humidity indicator card and desiccant pack. The humidity indicator should be below 30%RH.

REVISION HISTORY
DATE 1/27/04 8/12/08
REVISION A 1.0.0
DESCRIPTION Implemented tracking revision. SP507 is no longer available in MQFP package per PCN 07-110206a. In addition, SP507 is now only available in a Pb-Free, RoHS compliant package. MQFP package drawing has been replaced with the LQFP package drawing. Ordering information has been updated. Changed to Exar datasheet format and revision to 1.0.0.
