? semiconductor components industries, llc, 2006 may, 2006 ? rev. 5 1 publication order number: nlsf3t126/d nlsf3t126 quad bus buffer with 3?state control inputs the nlsf3t126 is a high speed cmos quad bus buffer fabricated with silicon gate cmos technology. it achieves noninverting high speed operation similar to equivalent bipolar schottky ttl while maintaining cmos low power dissipation. the nlsf3t126 requires the 3?state control input (oe) to be set low to place the output into high impedance. the t126 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 nlsf3t126 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 ? pb?free package is available* l h x h h l function table inputs output aoe l h z y *for additional information on our pb?free strategy and soldering details, please download the on semiconductor soldering and mounting techniques reference manual, solderrm/d. http://onsemi.com marking diagram device package shipping ? ordering information nlsf3t126mnr2 qfn?16 3000/tape & ree l ?for information on tape and reel specifications, including part orientation and tape sizes, please refer to our t ape and reel packaging specification s brochure, brd8011/d. nlsft126 = device code a = assembly location l = wafer lot y = year w = work week = pb?free package (note: microdot may be in either location) 16 nlsf t126 alyw 1 ??? ??? qfn?16 case 485g 1
