? semiconductor components industries, llc, 2001 april, 2001 rev. 1 1 publication order number: mc74lvx257/d mc74lvx257 quad 2-channel multiplexer with 3-state outputs the mc74lvx257 is an advanced high speed cmos quad 2channel multiplexer fabricated with silicon gate cmos technology. it consists of four 2input digital multiplexers with common select (s) and enable (oe ) inputs. when (oe ) is held high, selection of data is inhibited and all the outputs go low. the select decoding determines whether the a or b inputs get routed to the corresponding y outputs. the inputs tolerate voltages up to 7 v, allowing the interface of 5 v systems to 3 v systems. ? high speed: t pd = 4.5 ns (typ) at v cc = 3.3 v ? low power dissipation: i cc = 4 m a (max) at t a = 25 c ? high noise immunity: v nih = v nil = 28% v cc ? power down protection provided on inputs ? balanced propagation delays ? designed for 2 v to 5.5 v operating range ? low noise: v olp = 0.8 v (max) ? pin and function compatible with other standard logic families ? latchup performance exceeds 300 ma ? esd performance: hbm > 2000 v; machine model > 200 v ? chip complexity: fets = 100; equivalent gates = 25 so16 http://onsemi.com so16 d suffix case 751b marking diagrams 1 8 9 16 1 8 16 9 lvx257 awlyww lvx257 alyw tssop16 dt suffix case 948f ordering information eiaj so16 m suffix case 966 lvx257 alyw a = assembly location l, wl = wafer lot y = year w, ww = work week 16 9 1 8 device package shipping mc74lvx257d so16 48 units/rail mc74lvx257dt tssop16 96 units/rail mc74lvx257m eiaj so16 50 units/rail mc74lvx257dr2 2500 tape & reel mc74lvx257dtr2 tssop16 2500 tape & reel mc74lvx257mel 2000 tape & reel eiaj so16
