the mc74vhct138a is an advanced high speed cmos 3to8 decoder fabricated with silicon gate cmos technology. it achieves high speed operation similar to equivalent bipolar schottky ttl while maintaining cmos low power dissipation. when the device is enabled, three binary select inputs (a0 a2) determine which one of the outputs (y0 y7 ) 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. the vhct inputs are compatible with ttl levels. this device can be used as a level converter for interfacing 3.3v to 5.0v, because they have full 5v cmos level output swings. the vhct138a input structures provide protection when voltages between 0v and 5.5v are applied, regardless of the supply voltage. the output structures also provide protection when v cc = 0v. these input and output structures help prevent device destruction caused by supply voltage input/output voltage mismatch, battery backup, hot insertion, etc. ? high speed: t pd = 7.6ns (typ) at v cc = 5v ? low power dissipation: i cc = 4 m a (max) at t a = 25 c ? ttlcompatible inputs: v il = 0.8v; v ih = 2.0v ? power down protection provided on inputs and outputs ? balanced propagation delays ? designed for 4.5v to 5.5v operating range ? pin and function compatible with other standard logic families ? latchup performance exceeds 300ma ? esd performance: hbm > 2000v; machine model > 200v ? chip complexity: 122 fets or 30.5 equivalent gates pin assignment 13 14 15 16 9 10 11 12 5 4 3 2 1 8 7 6 a0 e1 a2 a1 y7 e3 e2 gnd y3 y2 y1 y0 v cc y5 y4 y6 http://onsemi.com device package shipping ordering information mc74vhct138ad soic16 48 units/rail mc74vhct138adr2 soic16 2500 units/reel mc74vhct138adt tssop16 96 units/rail mc74vhct138adtr2 tssop16 2500 units/reel mc74vhct138am soic eiaj16 48 units/rail mc74vhct138amel soic eiaj16 2000 units/reel soic16 d suffix case 751b tssop16 dt suffix case 948f soic eiaj16 m suffix case 966 1 8 9 16 1 8 16 9 1 16 9 8 vhct138a awlyyww marking diagrams vhct 138a awlyww vhct138a alyw a = assembly location wl = wafer lot yy = year ww = work week a = assembly location l = wafer lot y = year w = work week a = assembly location wl = wafer lot y = year ww = work week
