? semiconductor components industries, llc, 2006 june, 2006 ? rev. 1 1 publication order number: mc74vhct393a/d mc74vhct393a advance information dual 4?bit binary ripple counter the mc74vhct393a is an advanced high speed cmos dual 4 ? bit binary ripple counter fa bricated 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 4 ? bit binary ripple counters with parallel outputs from each counter stage. a 256 counter can be obtained by cascading the two binary counters. internal flip ? flops are triggered by high ? to ? low transitions of the clock input. reset for the counters is asynchronous and active ? high. state changes of the q outputs do not occu r simultaneously because of internal ripple delays. therefore, decoded out put signals are subject to decoding spikes and should not be used as cloc ks or as strobes except when gated with the clock of the vhc393. the vhct inputs are compatible with ttl levels. this device can be used as a level converter for interfacing 3.3 v to 5.0 v because it has full 5 v cmos level output swings. the vhct393a input structures provide protection when voltages between 0 v and 5.5 v are applied, regardless of the supply voltage. the output structures also provide protection when v cc = 0 v. these input and output structures help prevent device destruction caused by supply voltage?input/output voltage mismatch, battery backup, hot insertion, etc. the internal circuit is composed of three stages, including a buffer output which provides high noise immunity and stable output., the inputs tolerate voltages up to 7 v, allowing the interface of 5 v systems to 3 v systems. ? high speed: f max = 170mhz (typ) at v cc = 5v ? low power dissipation: i cc = 4 a (max) at t a = 25 c ? ttl ? compatible inputs: v il = 0.8 v; v ih = 2.0 v ? power down protection provided on inputs and outputs ? 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 pin assignment 11 12 13 14 8 9 10 5 4 3 2 1 7 6 2qb 2qa rd2 v cc 2qd 2q c 1qb 1qa rd1 cp1 gnd 1qc 1qd this document contains information on a new product. specifications and information herein are subject to change without notice. http://onsemi.com marking diagrams ordering information a = assembly location l = wafer lot y = year w = work week a = assembly location wl = wafer lot y = year ww = work week soic ? 14 d suffix case 751a tssop ? 14 dt suffix case 948g soic eiaj ? 14 m suffix case 965 1 7 8 14 8 14 7 1 1 14 8 7 vhct393a awlyww vhct 393a awlyww vhct393a alyw device package shipping MC74VHCT393AD soic ? 16 55 units/rail MC74VHCT393ADr2 soic ? 16 1000 units/reel MC74VHCT393ADt tssop ? 16 96 units/rail mc74vhct393am soic eiaj ? 16 50 units/rail mc74vhct393amel soic eiaj ? 16 2000 units/reel MC74VHCT393ADtr2 tssop ? 16 2500 units/reel
