Features L 信号处于高电平时,SDA 端口上的数据都是有效稳定的。只有当 SCL 信号处于低电平时,才 能改变 SDA 端口上的电平高低。 开始(重新开始)和停止工作条件 当 SCL 信号为高电平,SDA 信号由高电平转为低电平开始工作或者重新开始工作,而 SCL 信号为高 电平,SDA 信号由低电平转为高电平时停止工作。 字节格式 数据线的每个字节由 8 位组成。每个字节包含一个应答位。传输第一个数据是 MSB。 应答 在应答时钟期间,主机使 SDA 端口处于高电平,在写模式期间,ET7208 会发出应答信号使 SDA 端 口在应答期间处于低电平。在读模式期间,ET7208 不会发出应答信号从而使得 SDA 端口在应答期间处于 高电平。 图 4 I2C写模式 3/8 Rev 1.0 2009-10-14 ET7208 图 5 I2C读模式 注:ACK=应答信号 NOTACK=无应答信号 R/W =读/模式 MSB=字节的最高位 S=起始信号 RS=重新开始信号 P=停止信号 最大时钟速度=100KBITS/S Restart: 此时 SDA 电平翻转如波形中虚线所表示 I2C接口协议 写命令寄存器接口协议: R/ W 图 6 寄存器写模式 z 开始位 z 芯片地址字节=0110000b z 读写控制位 0b ( R/W ) z ACK=应答位 z 模式字节=(命令模式 0b ...

Etek Microelectronics
2- to 1-port analog switches
The ET7222 is 2­ to 1­port analog switches. Their wide bandwidth and low bit­to­bit skew allow them to pass high­speed differential signals with good signal integrity. Each switch is bidirectional and offers little or no attenuation of the high­ speed signals at the outputs. Industry­leading advantages include a propagation delay of less than 250 ps, resulting from its low channel resistance and low I/O capacitance. Their high channel­to­channel crosstalk rejection results in minimal noise interference. Their bandwidth is wide enough to pass High­Speed USB 2.0 differential signals (480 Mb/s).

QUAD DIFFERENTIAL LINE DRIVER
These line drivers are pin compatible with 26LS31 in applications where pin 4 = 5V and pin 12 = GND. Internal clamp diodes allow trouble-free operation when driving cable lengths exceeding 100m. Split supplies are provided to minimize standby power dissipation in high voltage applications. The logic should be powered from a regulated 5V supply at the VccBias pin. The output stages may then be powered by a separate supply at VccDrivers, up to 30V. Output voltage swings of 0.3V to VCC-1.9V are typical. The outputs are protected against shorts to ground, shorts to Vcc and to other outputs, by a two-fold scheme of current limiting and thermal shutdown. This assures highly reliable operation in h...

QUAD DIFFERENTIAL LINE DRIVER IC
These line drivers are similar in function to the ET7272, only in an open-collector format. The VCC pin powers the internal logic only. Output voltage is dependent on the customer supplied voltage, up to a maximum of 30V. There is essentially no difference in output swing or performance with VCC (LOGIC) values from 3.5V-30V. Internal clamp diodes allow trouble-free operation when driving cable lengths exceeding 100 meters. The outputs are protected by initiating shutdown when junciton temperatures...
