Any nG output control governs four BUS BUFF- ERS.OutputEnableinput(nG)tiedtogethergives full16-bitoperation. WhennGisLOW,theoutputsareon.WhennGis HIGH,theoutputareinhighimpedancestate. This device is designed to be used with 3 state memoryaddressdrivers,etc. The device circuits is including 26W series resis- tance in theoutputs. Theseresistors permit to re- ducelinenoiseinhighspeedapplications. All inputs and outputs are equipped with protec- tion circuits against static discharge, giving them 2KV ESDimmunityandtransientexcess voltage. February2003 1/10
