元器件交易网lips SemiconductorsProduct specificationHex inverting Schmitt-trigger with 5Vtolerant input74LVC14AFEATURESDESCRIPTION•Wide supply voltage range of: 1.2 V to 3.6 VThe 74LVC14A is a high-performance, low power, low-voltage•Si-gate CMOS device and superior to most advanced CMOSIn accordance with JEDEC standard no. 8-1Acompatible TTL families.•Inputs accept voltages up to 5.5 VInputs can be driven from either 3.3 V or 5 V devices. This feature•CMOS low power consumptionallows the use of these devices as translators in a mixed 3.3 V/5 Venvironment.•Direct interface with TTL levelsThe 74LVC14A provides six inverting buffers with Schmitt-triggeraction. It is capable of transforming slowly changing input signalsinto sharply defined, jitter-free output ATIONS•Wave and pulse shapers for highly noisy environments•Astable multivibrators•Monostable multivibratorsQUICK REFERENCE DATAGND = 0 V; Tamb = 25°C; tr ≤ tf ≤2.5 nsSYMBOLPARAMETERCONDITIONSTYPICALUNITtPHL/tPLHPropagation delaygyCnA to nYL = 50 pF;VCC = 3.3 V4nsCIInput capacitance3.5pFCPDPower dissipation capacitance per gateNotes 1 and 225pFNOTES: is used to determine the dynamic power dissipation (PD in µW)PD = CPD × VCC2 × fi )ȍ (CL × VCC2 × fo) where:fi = input frequency in MHz; CL = output load capacity in pF;fo = output frequency in MHz; V × VCC = supply voltage in V;ȍ (CLCC2 × fo) = sum of the condition is VI = GND to NG INFORMATIONPACKAGESTEMPERATURE RANGEOUTSIDE NORTH AMERICANORTH AMERICADWG NUMBER14-Pin PlasticSO–40°C to +85°C74LVC14A D74LVC14A DSOT108-114-Pin Plastic SSOP Type II–40°C to +85°C74LVC14A DB74LVC14A DBSOT337-114-Pin Plastic TSSOP Type I–40°C to +85°C74LVC14A PW74LVC14APW DHSOT402-1PIN CONFIGURATIONPIN DESCRIPTIONPIN NUMBERSYMBOLNAME AND FUNCTION1A114VCC1, 3, 5, 9, 11, 131A – 6AData inputs1Y2136A2, 4, 6, 8, 10, 121Y – 6YData outputs2A3126Y7GNDGround (0 V)2Y4115A14VCCPositive supply voltage3A5105Y3Y694AGND784YSV003961998 Apr 282853-1907 19308
