| 电路数Number of Circuits | 4 x 2:1 |
| 输入数Number of Inputs | 1 |
| 电源电压VccVoltage - Supply | |
| 静态电流IqCurrent - Quiescent (Max) | 单电源 Single Supply |
| 输出高，低电平电流Current - Output High, Low | 4.0V ~ 5.5 V |
| 低逻辑电平Logic Level - Low | The SN74CBT3257 is a 4-bit 1-of-2 high-speed TTL-compatible FET multiplexer/demultiplexer. The low on-state resistance of the switch allows connections to be made with minimal propagation delay.Output-enable (OE) and select-control (S) inputs select the appropriate B1 and B2 outputs for the A-input data. 5-Ω Switch Connection Between Two Ports TTL-Compatible Input Levels |
| 高逻辑电平Logic Level - High | SN74CBT3257是一个4位的1-2-TTL兼容的高速场效应管多路复用器。低通态电阻的开关允许以最小的传播延迟连接。输出使能（OE）和选择控制（S）输入选择适当的B1和B2用于A输入数据的输出。 5Ω开关连接两个端口之间 TTL兼容的输入电平 |
