74HC595 中文芯片手册

74HC5958位移位寄存器与输出锁存器功能描述这种高速移位寄存器采用先进的硅栅CMOS技术。该装置具有高的抗干扰性和标准CMOS集成电路的低功率消耗，以及用于驱动15个LS-TTL负载的能力。此装置包含馈送一个8位D型存储寄存器的8位串行入，并行出移位寄存器。存储寄存器具有8TRI-STATEE输出。提供了用于两个移位寄存器和存储寄存器独立的时钟。移位寄存器有直接首要明确，串行输入和串行输出（标准）引脚级联。两个移位寄存器和存储寄存器的使用正边沿触发的时钟。如果两个时钟被连接在一起时，移位寄存器的状态将总是提前存储寄存器的一个时钟脉冲。该54HC/74HC逻辑系列就是速度，功能和引脚输出与标准54LS/74LS逻辑系列兼容。所有输入免受损害，由于静电放电由内部二极管钳位到VCC和地面。产品特点1低静态电流：80mA最大值（74HC系列）2低输入电流为1mA最大38位串行输入，并行出移位寄存器以存储4宽工作电压范围：2V+6V5级联6移位寄存器直接明确7保证移频率：DC至30兆赫ConnectionDiagramTruthTableRCKSCKSCLRGFunotionXXXHQathruQh=TRI-STATEXXLLShiftRegisterclearedQ'h=oXTHLShiftRegisterclockedQn=Qp-1,Qq=SERTXHLContentsofShiftRegistertransferredtooutputlatchesAbsoluteMaximumRatings(Notes1&2)OperatingConditionsIfMilitary/Aerospacespecifieddevicesarerequired,MinMaxUnitspleasecontacttheNationalSemiconductorSalesSupplyVoltage(VCc)26VOffice/Distributorsforavailabilityandspecifications.DCInputorOutputVoltage0VccVSupplyVoltage(Vqc)-0.5to+7.0V(Vin,Vqut)DCInputVoltage(Vin)-1.5toVcc+1・5VOperatingTemp.Range(Ta)DCOutputVoltage(Vout)—0.5toVcc+0.5VMM74HC-40+85°CClampDiodeCurrent(Iik，Iok)±20mAMM54HC-55+125°CDCOutputCurrent,perpin(Iqut)±35mAInputRiseorFallTimes(t“tf)Vcc=2.0VVqC=4.5V1000nsDCVqcorGNDCurrent,perpin(Iqc)±70mA500nsStorageTemperatureRange(Tstg)PowerDissipation(Pd)-65°Cto+150°CVqC=6.0V400ns(Note3)600mWS.O.Packageonly500mWLeadTemp.(TJ(Soldering10seconds)260°C
