74系列芯片后缀的意义

74系列芯片后缀的意义

74系列TTL数字逻辑集成电路系国际上通用的标准电路。

其品种共分为六大类即74xx(标准)74LSxx(低功耗肖特基)74Sxx(肖特基)74ALSxx(先进低功耗肖特基)74ASxx(先进肖特基)74Fxx(高速)只要序列号相同,则逻辑功能完全相同。

另外还出现了74系列高速CMOS电路,该系列共分三大类,即HC(CMOS工作电平)HCT(TTL工作电平,可与74LS系列互换使用)HCU(适用于无缓冲级的CMOS电路)74系列高速CMOS电路的逻辑功能与外引线排列与相应的74LS系列完全相同,工作速度也相当,而功耗大大降低。

上面这个是比较老的,不过也算最常用的了。

下面有个比较全的:BiPolarALS = Advanced Low-Power Schottky LogicAS = Advanced Schottky LogicF = Fast LogicLS = Low-Power Schottky LogicS = Schottky LogicBiCMOSBCT = BiCMOS TechnologyABT = Advanced BiCMOS TechnologyALB = Advanced Low-Voltage BiCMOSLVT = Low-Voltage BiCMOS TechnologyALVT = Advanced Low-Voltage CMOS TechnologyCMOSAC = Advanced CMOS LogicACT = Advanced CMOS LogicFCT = Fast CMOS TechnologyHC = High-Speed CMOS LogicAHC = Advanced High-Speed CMOSVHC = Advanced High-Speed CMOSHCT = High-Speed CMOS LogicAHCT = Advanced High-Speed CMOSVHCT = Advanced High-Speed CMOSLVC = Low-Voltage CMOS TechnologyALVC = Advanced Low-Voltage CMOS Technology----------------------------------------74HC和和74AHC的区别,因为上面只说到了Advanced,到底是哪里Advanced呢?以下回答是网上找的,仅供参考:之所以选用74AHC,是因为它通常提供了更低的VCC允许值,使得可以兼容更低电平的门限。

Product DescriptionPericom Semiconductor’s PI74LVC series of logic circuits are produced using the Company’s advanced submicron CMOS tech-nology, achieving industry leading speed.The PI74LVC4245A is a non-inverting 8-bit Bidirectional Trans-ceiver that uses two separate power supply rails. A-port (V CCA ) is set to operate at 5V and B-port (V CCB ) is set to operate at 3.3V . This allows for translation from a 3.3V to a 5Venvironment and vice-versa. This tranceiver is designed for asynchronous two-way communication between data buses. The direction control input pin (DIR) determines the dataflow from the A bus to the B bus or from the B bus to the A bus. The output enable (OE) input, when HIGH,disables both A and B ports by placing them in HIGH Z condi-tion.8-Bit Dual Supply Bus Transceiverwith 3-State OutputsProduct Features• 4.5V to 5.5V on A-port and 2.7V to 3.6V on B-port • Latch-up performance exceeds 200mA Per JESD78• ESD protection exceeds JESD 22- 2000V Human-Body Model (A114-B) - 200V Machine Model (A115-A)• Industrial Temperature: –40°C to +85°C • Available Packages:- 24-pin 173-mil wide plastic TSSOP (L) - 24-pin 150-mil wide plastic QSOP (Q) - 24-pin 300-mil wide plastic SOIC (S)PI74LVC4245AADV ANCE INFORMATIONTruth Table (1)Note:1.

Connect ground first before any supply voltage is applied.2. Then Power up V CCA , which is the control side of the device.3. Ramp OE ahead of or with V CCA to help prevent bus contention4. Ramp DIR with V CCA if DIR HIGH is needed (A bus to B bus). Otherwise keep DIR LOW.Note:8. Skew between any two outputs of the same device, switching in the same direction.
