輸出高電平，低電平電流 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	具有三態輸出的八路總線收發器描述/訂購信息（續） 'LV245A設備是專為數據總線之間的異步通信。該裝置發送數據從A總線到B總線或從B總線到A總線，這取決于對邏輯電平方向控制（DIR）輸入。輸出使能（OE）輸入可用于禁用設備，以便巴士有效隔離。為了確保在開機或斷電高阻抗狀態，OE應當連接到VCC通過上拉電阻，電阻的最小值確定的驅動器的電流吸收能力。這些器件是完全指定部分斷電應用程序使用IOFF IOF電路將禁用輸出，防止損壞電流回流通過這些器件的時候都斷電。 “2 V至5.5 V的VCC操作最大5 V時為6.5 ns噸典型的VoIP（輸出地彈跳） <0.8 V在VCC =3.3 V，TA= 25°C 典型的VOHV（輸出VOH沖） >2.3 V在VCC =3.3 V，TA= 25°C 支持混合模式的工作電壓關閉所有端口支持部分掉電模式手術閉鎖性能超過250 mA每 JESD17 ESD保護超過JESD22 2000-V人體模型（A114-A） 200-V機型號（A115-A） 1000-V帶電器件模型（C101“
