| 低逻辑电平 Logic Level - Low | The SN74CB3T3306 is a high-speed TTL-compatible FET bus switch with low ON-state resistance (ron), allowing for minimal propagation delay. The device fully supports mixed-mode signal operation on all data I/O ports by providing voltage translation that tracks VCC. The SN74CB3T3306 supports systems using 5-V TTL, 3.3-V LVTTL, and 2.5-V CMOS switching standards, as well as user-defined switching levels . The SN74CB3T3306 is organized as two 1-bit bus switches with separate ouput-enable (1OE, 2OE) inputs. It can be used as two 1-bit bus switches or as one 2-bit bus switch. When OE is low, the associated 1-bit bus switch is ON, and the A port is connected to the B port, allowing bidirectional data flow between ports. When OE is high, the associated 1-bit bus switch is OFF, and a high-impedance state exists between the A and B ports. Output Voltage Translation Tracks VCC Supports Mixed-Mode Signal Operation on All Data I/O Ports – 5-V Input Down to 3.3-V Output Level Shift With 3.3-V VCC – 5-V/3.3-V Input Down to 2.5-V Output Level Shift With 2.5-V VCC 5-V Tolerant I/Os With Device Powered Up or Powered Down Bidirectional Data Flow With Near-Zero Propagation Delay Low ON-State Resistance (ron)，Characteristics (ron = 5 Ω Typ) Low Input/Output Capacitance Minimizes Loading (Cio(OFF) = 4.5 pF Typ) Data and Control Inputs Provide Undershoot Clamp Diodes |
| 高逻辑电平 Logic Level - High | 的SN74CB3T3306是一个高速TTL兼容FET总线开关具有低导通电阻（RON），允许最小的传播延迟。通过提供跟踪VCC的电压转换，该设备在所有的数据I/O端口上完全支持混合信号操作模式。SN74CB3T3306支持系统使用5-V TTL，LVTTL3.3-V，2.5 V CMOS开关标准，以及用户定义的切换水平。SN74CB3T3306被组织为两个1位总线开关，有着单独的输出使能（1OE，2OE）。它可用于两个1位总线开关或作为一个2 - 位总线开关。当OE为低时，相关的1位总线开关接通，被连接到A端口和B端口，允许双向数据端口之间流动。当OE高，相关的1 - 位总线开关关闭，高阻抗状态之间存在A和B的端口。 输出电压转换跟踪VCC 所有的数据I / O端口上支持混合信号操作模式 - 5 V输入至3.3 V输出电平移位与3.3-V VCC - 5-V/3.3-V输入下降到2.5 V的输出电平移位与2.5 V的VCC 5-V容限的I/O与设备通电或断电 双向数据流的近零传播延迟 低导通电阻（Ron），特性（RON=5Ω（典型值）） 低输入/输出电容最小化 装载（CIO（关）=4.5 pF（典型值）） 数据和控制输入提供 冲钳位二极管 |
