? semiconductor components industries, llc, 2012 april, 2012 ? rev. 7 1 publication order number: nl37wz17/d nl37wz17 triple noninverting schmitt-trigger buffer the nl37wz17 is a high performance buffer with schmitt ? trigger inputs operating from a 1.65 to 5.5 v supply. the nl37wz17 can be used as a line receiver which will receive slow input signals. the nl37wz17 is capable of transforming slowly changing input signals into sharply defined, jitter ? free output signals. in addition, it has a greater noise margin than conventional inverters. the nl37wz17 has hysteresis between the positive ? going and the negative ? going input thresholds (typically 1.0 v) which is determined internally by transistor ratios and is essentially insensitive to temperature and supply voltage variations. features ? designed for 1.65 v to 5.5 v v cc operation ? over voltage tolerant inputs and outputs ? lvttl compatible ? interface capability with 5 v ttl logic with v cc = 3 v ? lvcmos compatible ? 24 ma balanced output sink and source capability ? near zero static supply current substantially reduces system power requirements ? current drive capability is 24 ma at the outputs ? chip complexity: fet = 94 ? these devices are pb ? free and are rohs compliant in a2 out y2 figure 1. pinout figure 2. logic symbol out y1 in a1 out y3 in a3 v cc in a1 out y3 gnd in a2 out y2 1 2 3 8 7 6 in a3 out y1 45 1 1 1 ordering information marking diagram us8 us suffix case 493 http://onsemi.com 1 8 lx = device code m = date code* = pb ? free package lx m *date code orientation may vary depending upon manufacturing location.
