HD74HC245FP  的参数

逻辑类型 Logic Type 收发器,非反相 Transceiver, Non-Inverting
元件数 Number of Elements 1
每元件位数 Number of Bits per Element 8
1.2 V ~ 3.6 V
电源电压 Voltage - Supply 24mA,24mA
输出高电平,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
Description & Applications 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
