? semiconductor components industries, llc, 2002 june, 2002 rev. 5 1 publication order number: mc74vhc393/d mc74vhc393 dual 4-bit binary ripple counter the mc74vhc393 is an advanced high speed cmos dual 4bit binary ripple counter fabricated with silicon gate cmos technology. it achieves high speed operation similar to equivalent bipolar schottky ttl while maintaining cmos low power dissipation. this device consists of two independent 4bit binary ripple counters with parallel outputs from each counter stage. a 256 counter can be obtained by cascading the two binary counters. internal flipflops are triggered by hightolow transitions of the clock input. reset for the counters is asynchronous and activehigh. state changes of the q outputs do not occur simultaneously because of internal ripple delays. therefore, decoded output signals are subject to decoding spikes and should not be used as clocks or as strobes except when gated with the clock of the vhc393. the inputs tolerate voltages up to 7 v, allowing the interface of 5 v systems to 3 v systems. ? high speed: f max = 170 mhz (typ) at v cc = 5 v ? low power dissipation: i cc = 4 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: 236 fets or 59 equivalent gates marking diagrams ordering information a = assembly location l, wl = wafer lot y = year w, ww = work week soic14 d suffix case 751a tssop14 dt suffix case 948g soic eiaj14 m suffix case 965 1 7 8 14 8 14 7 1 1 14 8 7 vhc393 awlyww vhc 393 awlyww vhc393 alyw device package shipping mc74vhc393d soic14 55 units/rail mc74vhc393dt tssop14 96 units/rail mc74vhc393m soic eiaj14 50 units/rail mc74vhc393mel soic eiaj14 2000 units/reel mc74vhc393dtr2 tssop14 2500 units/reel http://onsemi.com
