| 低逻辑电平Logic Level - Low | The NC7WB3125 is a 2-bit ultra high-speed CMOS FET bus switch with TTL-compatible active LOW control inputs. The low On Resistance of the switch allows inputs to be connected to outputs with minimal propagation delay and without generating additional ground bounce noise. The device is organized as a 2-bit switch with independent bus enable (OE) controls. When OE is LOW, the switch is ON and Port A is connected to Port B. When OE is HIGH, the switch is OPEN and a high-impedance state exists between the two ports. Control inputs tolerate voltages up to 5.5V independent of VCC.

| 高逻辑电平Logic Level - High | NC7WB3125是一个2位的超高速CMOS FET总线开关与TTL兼容的低电平控制输入。低导通电阻的开关以最小的传播延迟和不产生额外地弹噪声允许输入连接到输出。该设备被组织作为一个独立的总线使能（OE）控制的2位开关。当OE为低电平时，开关导通和端口连接到端口B。当OE为高电平时，开关打开和高阻抗状态之间存在着两个端口。控制耐输入电压高达5.5V，独立于VCC。 US8表面贴装封装节省空间 MicroPakTM无铅无铅封装 典型3Ω开关电阻，在5.0V VCC时 最小的传播延迟通过开关 断电高阻抗输入/输出 流经零反弹模式 TTL兼容的低电平控制输入 控制输入过压容限 总线开关更换逻辑X125部分 |
