74lvc14a document number: ds35262 rev. 3 - 2 1 of 10 www.diodes.com july 2012 ? diodes incorporated 74lvc14a hex inverters with schmitt trigger inputs description the 74lvc14a provides six independent schmitt trigger inverter buffers. the device is designed for operation with a power supply range of 1.65v to 5.5v. the inputs are tolerant to 5.5v allowing this device to be used in a mixed voltage environment. the device is fully specified for partial power down applications using ioff. the ioff circuitry disables t he output preventing damaging current backflow when the device is powered down. the gates perform the positive boolean function: ay = features ? wide supply voltage range from 1.65v to 5.5v ? outputs sink or source 24ma at v cc = 3.3v ? cmos low power consumption ? ioff supports partial-power-down mode operation ? inputs or outputs accept up to 5.5v ? inputs can be driven by 3.3 v or 5.5v allowing for voltage translation applications. ? esd protection exceeds jesd 22 ? 200-v machine model (a115-a) ? 2000-v human body model (a114-a) ? exceeds 1000-v charged device model (c101c) ? latch-up exceeds 250ma per jesd 78, class ii ? range of package options so-14 and tssop-14 ? totally lead-free & fully rohs compliant (notes 1 & 2) ? halogen and antimony free. ?green? device (note 3) ? ? pin assignments applications ? voltage level shifting ? general purpose logic ? power down signal isolation ? wide array of products such as: ? pcs, networking, notebooks, ultrabooks, netbooks ? computer peripherals, hard drives, cd/dvd rom ? tv, dvd, dvr, set top box notes: 1. no purposely added lead. fully eu directiv e 2002/95/ec (rohs) & 2011/6 5/eu (rohs 2) compliant. 2. see http://www.diodes.com for more in formation about diodes incorpor ated?s definitions of halogen- and antimony-free, "gree n" and lead-free. 3. halogen- and antimony-free "green? products are defined as those which contain <900ppm br omine, <900ppm chlorine (<1500ppm t otal br + cl) and <1000ppm antimony compounds.
