? semiconductor components industries, llc, 2001 june, 2001 rev. 2 1 publication order number: mc74vhct14a/d mc74vhct14a hex schmitt inverter the mc74vhct14a is an advanced high speed cmos schmitt inverter fabricated with silicon gate cmos technology. it achieves high speed operation similar to equivalent bipolar schottky ttl while maintaining cmos low power dissipation. pin configuration and function are the same as the mc74vhct04a, but the inputs have hysteresis and, with its schmitt trigger function, the vhct14a can be used as a line receiver which will receive slow input signals. 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 it has full 5v cmos level output swings. the vhct14a 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. 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 7v, allowing the interface of 5v systems to 3v systems. ? high speed: t pd = 5.5ns (typ) at v cc = 5v ? low power dissipation: i cc = 2 m a (max) at t a = 25 c ? ttlcompatible inputs: v il = 0.8v; v ih = 2.0v ? 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 ? chip complexity: 60 fets or 15 equivalent gates figure 1. logic diagram y1 a1 a2 a3 a4 a5 a6 y2 y3 y4 y5 y6 1 3 5 9 11 13 2 4 6 8 10 12 y = a 14lead soic d suffix case 751a http://onsemi.com 14lead tssop dt suffix case 948g pin connections device package shipping ordering information mc74vhct14ad soic 55 units/rail mc74vhct14adt tssop 96 units/rail 14lead soic eiaj m suffix case 965 mc74vhct14am soic eiaj 50 units/rail 13 14 12 11 10 9 8 2 1 34567 v cc a6 y6 a5 y5 a4 y4 a1 y1 a2 y2 a3 y3 gnd l h function table inputs outputs a h l y pinout: 14lead packages (top view)
