电路配置Circuit| 1 x SPDT \---|--- 导通电阻On-State Resistance| 15 Ω/Ohm 电源电压Voltage Supply Source| 1.65 V ~ 5.5 V Description & Applications| Low Voltage SPDT Analog Switch or 2:1 Multiplexer/Demultiplexer Bus Switch General Description The NC7SB3157 or FSA3157 is a high performance, single-pole/double-throw (SPDT) Analog Switch or 2:1 Multiplexer/Demultiplexer Bus Switch. The device is fabricated with advanced sub-micron CMOS technology o achieve high speed enable and disable times and low On Resistance. The break before make select circuitryprevents disruption of signals on the B Port due to both switches temporarily being enabled during select pin switching. The device is specified to operate over the 1.65 to 5.5V VCC operating range. The control input tolerates voltages up to 5.5V independent of the VCC operating range. Features Useful in both analog and digital applications Space saving SC70 6-lead surface mount package Ultra small MicroPak™ Pb-Free leadless package Low On Resistance; < 10Ω on typ @ 3.3V VCC Broad VCC operating range; 1.65V to 5.5V Rail-to-Rail signal handling Power down high impedance control input Overvoltage tolerance of control input to 7.0V Break before make enable circuitry 250 MHz, 3dB bandwidth 描述与应用| 低电压SPDT模拟开关或 2:1多路复用器/多路解复用器总线开关 概述 该NC7SB3157或FSA3157是一种高性能，单刀双掷（SPDT）模拟开关或2:1多路复用器/多路解复用器总线开关。该设备是 制造与先进的亚微米CMOS技术Ø实现高速启用和禁用时间和低导通电阻。 先断后选择电路 防止干扰信号B端口，由于这两个 暂时启用交换机在选择引脚 开关。该设备被指定为工作在 1.65至5.5V的VCC工作范围。容忍控制输入电压高达5.5V VCC工作范围内独立。 在模拟和数字应用非常有用 SC70 6引脚表面贴装封装节省空间 超小型MicroPak™标准无铅无铅封装 低导通电阻<10Ω上typ@3.3V VCC 宽VCC工作范围1.65V至5.5V; 轨到轨信号处理 高阻抗控制输入掉电 控制输入​​到7.0V的过电压耐受性 先断后使电路 250兆赫，3dB带宽
