输出高电平，低电平电流 Current - Output High, Low	OCTAL BUS TRANSCEIVERS WITH 3-STATE OUTPUTS description/ordering information (continued) The ’LV245A devices are designed for asynchronous communication between data buses. The device transmits data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable (OE) input can be used to disable the device so the buses are effectively isolated. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. These devices are fully specified for partial-power-down applications using Ioff The Iof circuitry disables the outputs, preventing damaging current backflow through the devices when they are powered down. 2-V to 5.5-V VCC Operation Max tpd of 6.5 ns at 5 V Typical VOLP (Output Ground Bounce) <0.8 V at VCC = 3.3 V, TA = 25°C Typical VOHV (Output VOH Undershoot) >2.3 V at VCC = 3.3 V, TA = 25°C Support Mixed-Mode Voltage Operation on All Ports off Supports Partial-Power-Down Mode Operation Latch-Up Performance Exceeds 250 mA Per JESD 17 ESD Protection Exceeds JESD 22 2000-V Human-Body Model (A114-A) 200-V Machine Model (A115-A) 1000-V Charged-Device Model (C101
Description & Applications	具有三态输出的八路总线收发器描述/订购信息（续） 'LV245A设备是专为数据总线之间的异步通信。该装置发送数据从A总线到B总线或从B总线到A总线，这取决于对逻辑电平方向控制（DIR）输入。输出使能（OE）输入可用于禁用设备，以便巴士有效隔离。为了确保在开机或断电高阻抗状态，OE应当连接到VCC通过上拉电阻，电阻的最小值确定的驱动器的电流吸收能力。这些器件是完全指定部分断电应用程序使用IOFF IOF电路将禁用输出，防止损坏电流回流通过这些器件的时候都断电。 “2 V至5.5 V的VCC操作最大5 V时为6.5 ns吨典型的VoIP（输出地弹跳） <0.8 V在VCC =3.3 V，TA= 25°C 典型的VOHV（输出VOH冲） >2.3 V在VCC =3.3 V，TA= 25°C 支持混合模式的工作电压关闭所有端口支持部分掉电模式手术闭锁性能超过250 mA每 JESD17 ESD保护超过JESD22 2000-V人体模型（A114-A） 200-V机型号（A115-A） 1000-V带电器件模型（C101“
