3-to-8 line decoder with 5vtolerant inputs the mc74lvx138 is an advanced high speed cmos 3to8 line decoder. the inputs tolerate voltages up to 7v, allowing the interface of 5v systems to 3v systems. when the device is enabled, three binary select inputs (a0 a2) determine which one of the outputs (o0 o7 ) will go low. when enable input e3 is held low or either e2 or e1 is held high, decoding function is inhibited and all outputs go high. e3, e2 , and e1 inputs are provided to ease cascade connection and for use as an address decoder for memory systems. ? high speed: t pd = 5.5ns (typ) at v cc = 3.3v ? low power dissipation: i cc = 4 m a (max) at t a = 25 c ? power down protection provided on inputs ? balanced propagation delays ? low noise: v olp = 0.5v (max) ? pin and function compatible with other standard logic families ? latchup performance exceeds 300ma ? esd performance: hbm > 2000v; machine model > 200v figure 1. 16lead pinout (top view) 15 16 14 13 12 11 10 2 1 34567 v cc 9 8 o0 o1 o2 o3 o4 o5 o6 a0 a1 a2 e1 e2 e3 o7 gnd lvx mc74lvx138 lowvoltage cmos d suffix 16lead soic package case 751b05 dt suffix 16lead tssop package case 948f01 m suffix 16lead soic eiaj package case 96601 pin names function address inputs enable inputs enable input outputs pins a0a2 e1 e2 e3 o0 o7 ? semiconductor components industries, llc, 2001 february, 2001 rev. 1 1 publication order number: mc74lvx138/d
