? semiconductor components industries, llc, 2011 june, 2011 ? rev. 5 1 publication order number: nlsf3t125/d nlsf3t125 quad bus buffer with 3 ? state control inputs the nlsf3t125 is a high speed cmos quad bus buffer fabricated with silicon gate cmos technology. it achieves high speed operation similar to equivalent bipolar schottky ttl while maintaining cmos low power dissipation. the nlsf3t125 requires the 3 ? state control input (oe ) to be set high to place the output into the high impedance state. the t125 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 5.0 v cmos level output swings. the nlsf3t125 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 7.0 v, allowing the interface of 5.0 v systems to 3.0 v systems. features ? high speed: t pd = 3.8 ns (typ) at v cc = 5.0 v ? low power dissipation: i cc = 4.0 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 ? balanced propagation delays ? designed for 2.0 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: human body model; > 2000 v, machine model; > 200 v ? chip complexity: 72 fets or 18 equivalent gates ? these devices are pb ? free and are rohs compliant nlsf3t125 inputs output function table y aoe h l x l l h h l z marking diagram qfn ? 16 case 485g http://onsemi.com nlsf3t125 = specific device code a = assembly location l = wafer lot y = year w = work week = pb ? free package nlsf3 t125 alyw (note: microdot may be in either location) 1 ordering information device qfn ? 16 (pb ? free) shipping ? 3000/tape & reel nlsf3t125mnr2g package ?for information on tape and reel specifications, including part orientation and tape sizes, please refer to our t ape and reel packaging specifications brochure, brd8011/d.
