CAT5110/18/19/23/24/25 linear-taper digitally programmable potentiometers perform the same function as a mechanical potentiometer or a variable resistor. These devices consist of a fixed resistor and a wiper contact with 32-tap points that are digitally controlled through a2-wire up/down serial inte ...

arm指令集(1) 　ARM跳转指令可以从当前指令向前或向后的32MB地址空间跳转。这类跳转指令有以下4种。 　　（1）B 跳4专指令 　　B〔条件） （地址） 　　B指令属于ARM指令集，是最简单的分支指令。一旦遇到一个B指令，ARM处理器将立即跳转到给定的地址，从那里继续执行。注意：存储在分支指令中的实际值是相对当前R15的值 ...

The TL2575 and TL2575HV represent superior alternatives to popular three-terminal linear regulators. Due totheir high efficiency, the devices significantly reduce the size of the heatsink and, in many cases, no heatsink isrequired. Optimized for use with standard series of inductors available from s ...

The Philips family of Multiplexers and Switches consists of bi-directional translating switches controlled via the I2C or SMBus to fan out an upstream SCL/SDA pair to 2, 4 or 8 downstream channels of SCx/SDx pairs. The Multiplexers allow only one downstream channel to be selected at a time, while th ...
