93L09 Dual 4-Input Multiplexer
June 1989
93L09 Dual 4-Input Multiplexer
General Description
The 93L09 monolithic dual 4-input digital multiplexers consist of two multiplexing circuits with common input select logic Each circuit contains four inputs and fully buffered t complementary outputs In addition to multiplexer operation he 93L09 can generate any two functions of three variables Active pullups in the outputs ensure high drive and high speed performance Because of its high speed performance and on-chip select decoding the 93L09 may be cascaded to multiple levels so that any number of lines can be multiplexed onto a single output bus

Functional Description
The 93L09 dual 4-input multiplexers are able to select two bits of either HIGH or LOW data or control from up to four sources in one package The 93L09 is the logical implementation of two-pole four-position switch with the position of the switch being set by the logic levels supplied to the two select inputs Both assertion and negation outputs are provided for both multiplexers The logic equations for the outZ uts are shown below p

The 93L09 is frequently used to move data from a group of registers to a common output bus The particular register from which the data came would be determined by the state of the select inputs A less obvious application is as a function generator The 93L09 can generate two functions of three variables This is useful for implementing random gating functions
