●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 高逻辑电平Logic Level - High| 传播延迟时间@Vcc，CLMax Propagation Delay @ V, Max CL| Description & Applications| 描述与应用|
