? semiconductor components industries, llc, 2001 april, 2001 rev. 2 1 publication order number: mc74vhc257/d mc74vhc257 quad 2-channel multiplexer with 3-state outputs the mc74vhc257 is an advanced high speed cmos quad 2channel multiplexer fabricated with silicon gate cmos technology. it achieves high speed operation similar to equivalent bipolar schottky ttl while maintaining cmos low power dissipation. 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 7v, allowing the interface of 5v systems to 3v systems. ? high speed: t pd = 4.1ns (typ) at v cc = 5v ? 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 2v to 5.5v operating range ? low noise: v olp = 0.8v (max) ? pin and function compatible with other standard logic families ? latchup performance exceeds 300ma ? esd performance: hbm > 2000v; machine model > 200v ? chip complexity: fets = 100; equivalent gates = 25 13 14 15 16 9 10 11 12 5 4 3 2 1 8 7 6 s y0 b0 a0 y1 b1 a1 gnd y3 b3 a3 oe v cc b2 a2 y2 figure 1. pin assignment so16 http://onsemi.com so16 d suffix case 751b marking diagrams 1 8 9 16 1 8 16 9 vhc257 awlyww vhc257 alyw tssop16 dt suffix case 948f ordering information eiaj so16 m suffix case 966 vhc257 alyw a = assembly location l, wl = wafer lot y = year w, ww = work week 16 9 1 8 device package shipping mc74vhc257d so16 48 units/rail mc74vhc257dt tssop16 96 units/rail mc74vhc257m eiajso16 50 units/rail mc74vhc257dr2 2500 tape & reel mc74vhc257dtr2 tssop16 2500 tape & reel mc74vhc257mel eiajso16 2000 tape & reel
