集成电路IC 总线收发器 HD74HC245FP SOP-20
逻辑类型Logic Type | 收发器,非反相 Transceiver, Non-Inverting |
电路数Number of Circuits | 1 |
输入数Number of Inputs | 8 |
电源电压VccVoltage - Supply | 1.2 V ~ 3.6 V |
静态电流IqCurrent - Quiescent (Max) | 24mA,24mA |
输出高,低电平电流Current - Output High, Low | Octal Bus Transceivers (with 3-state outputs) Description This device has an active low enable input G and a direction control input (DIR). When DIR is high, data flows from the A inputs to the B outputs. When DIR is low, data flows from the B inputs to the A outputs. The HD74HCT245 transfers true data from one bus to the other. This device does not have schmitt trigger inputs. Features • LSTTL Output Logic Level Compatibility as well as CMOS Output Compatibility • High Speed Operation: tpd (A to Y) = 12 ns typ (CL = 50 pF) • High Output Current: Fanout of 15 LSTTL Loads • Wide Operating Voltage: VCC = 4.5 to 5.5 V • Low Input Current: 1 µA max • Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C) • Ordering Information |
低逻辑电平Logic Level - Low | 八路总线收发器(三态输出) 描述 该器件具有一个低电平有效使能输入G和方向控制输入(DIR)。当DIR为高,数据流量 A输入B输出。当DIR低,B输入A输出的数据流。 HD74HCT245 传输真正的数据总线。 此设备不具有施密特触发输入 •输入通道输出逻辑电平兼容,以及CMOS输出兼容性 •高速运行:TPD(Y)=12 ns(典型值)(CL= 50 PF) •高输出电流:扇出的15输入通道负载 •宽工作电压:VCC=4.5到5.5 V •低输入电流:最大1μA •低静态电源电流:ICC(静态)= 4μA最大(大= 25°C) •订购信息 |
