Product introduction

DS2408An 8-channel, programmable I/O 1-Wire® chip

description

DS2408是一个8通道，可编程I / O的1-Wire®芯片。 PIO输出配置为漏极开路，并提供最大100Ω电阻。一个强大的PIO通道访问通信协议，确保无差错的发生，PIO输出设置更改。可以使用一个有效的数据选通输出锁存到外部电路，如一个D / A转换器（DAC）或微控制器的数据总线的PIO逻辑状态。

DS2408的操作控制的单导体的1-Wire总线。通信设备如下Dallas Semiconductor标准的1-Wire协议。每个DS2408的有自身的不可改变的和独特的64位ROM注册号，在出厂时芯片的光刻。登记编号，保证了独特的识别，是用来解决在一个多点的1-Wire网络环境的设备。多个DS2408的设备可以驻留在一个共同的1-Wire总线，可以彼此独立运作。 DS2408的也支持基于PIO状态或上电复位活动的1-Wire条件搜索能力，导致参与条件搜索的条件是可编程的。 DS2408的有一个可选的V_CC电源连接。当外部电源是缺席的，设备的电源供应，从1-Wire总线寄生。当外部电源是目前的PIO状态均保持在1-Wire总线电源的情况下。 RSTZ信号是可配置的服务作为一个硬连接PIO输出复位或外部电路频闪，表明已完成的PIO写或PIO读。

Key features
