? semiconductor components industries, llc, 2001 september, 2001 rev. 2 1 publication order number: mc74lcx139/d mc74lcx139 dual low-voltage cmos 2-to-4 decoder/demultiplexer with 5vtolerant inputs the mc74lcx139 is a high performance, 2to4 decoder/ demultiplexer operating from a 2.3 to 3.6 v supply. high impedance ttl compatible inputs significantly reduce current loading to input drivers while ttl compatible outputs offer improved switching noise performance. a v i specification of 5.5 v allows mc74lcx139 inputs to be safely driven from 5 v devices. the mc74lcx139 is suitable for memory address decoding and other ttl level bus oriented applications. the mc74lcx139 highspeed 2to4 decoder/demultiplexer accepts two binary weighted inputs (a0, a1) and, when enabled, provides four mutually exclusive activelow outputs. the lcx139 features an active low enable input. all outputs will be high unless en is low. the lcx139 can be used as an 8output demultiplexer by using one of the activelow enable inputs as the data input and the other enable input as a strobe. the enable inputs which are not used must be permanently tied to ground. current drive capability is 24 ma at the outputs. ? designed for 2.3 to 3.6 v v cc operation ? 5 v tolerant inputs interface capability with 5 v ttl logic ? lvttl compatible ? lvcmos compatible ? 24 ma balanced output sink and source capability ? near zero static supply current (10 m a) substantially reduces system power requirements ? latchup performance exceeds 500 ma ? esd performance: human body model >2000 v; machine model >200 v http://onsemi.com so16 d suffix case 751b marking diagrams 1 8 9 16 1 8 16 9 1 16 9 8 lcx139 awlyyww a = assembly location wl, l = wafer lot yy, y = year ww, w = work week lcx 139 awlyww lcx139 alyw tssop16 dt suffix case 948f eiaj so16 m suffix case 966 ordering information device package shipping mc74lcx139d so16 48 units/rail mc74lcx139dr2 so16 2500 units/reel mc74lcx139dt tssop16 96 units/rail mc74lcx139dtel tssop16 2000 units/reel mc74lcx139m eiaj so16 48 units/rail mc74lcx139mel 2000 units/reel mc74lcx139dtr2 tssop16 2000 units/reel eiaj so16
