? semiconductor components industries, llc, 2001 may, 2001 rev. 2 1 publication order number: mc74lcx258/d mc74lcx258 low-voltage cmos quad 2-input multiplexer with 5 vtolerant inputs and outputs (3state, inverting) the mc74lcx258 is a high performance, quad 2input inverting multiplexer with 3state outputs 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 mc74lcx258 inputs to be safely driven from 5v devices. four bits of data from two sources can be selected using the select input. the four outputs present the selected data in the inverted form. the outputs may be switched to a high impedance state by placing a logic high on the output enable (oe ) input. current drive capability is 24 ma at the outputs. ? designed for 2.3 to 3.6 v v cc operation ? 5 v tolerant interface capability with 5 v ttl logic ? supports live insertion and withdrawal ? i off specification guarantees high impedance when v cc = 0 v ? ttl compatible ? cmos compatible ? 24 ma balanced output sink and source capability ? near zero static supply current in all three logic states (10 m a) substantially reduces system power requirements ? latchup performance exceeds 500 ma ? esd performance: human body model >2000 v; machine model >200 v 2400 units/reel 2500 units/reel 48 units/rail 2400 units/reel 2000 units/reel http://onsemi.com so16 d suffix case 751b marking diagrams 1 16 lcx258 awlyww lcx 258 alyw tssop16 dt suffix case 948f ordering information eiaj so16 m suffix case 966 74lcx258 alyw device package shipping mc74lcx258d so16 48 units/rail mc74lcx258dr2 so16 mc74lcx258dtel tssop16 mc74lcx258m eiaj so16 mc74lcx258mel eiaj so16 mc74lcx258dtr2 tssop16 a = assembly location l, wl = wafer lot y = year w, ww = work week 1 16 1 16
