MAX4501/MAX4502 Low-Voltage, SPST, CMOS Analog Switches _________________General Description _____________________________Features
... The logic-level thresholds are CMOS/TTL compatible when V+ is +5V. As V+ rises, the threshold increases slightly. When V+ reaches +12V, the logic-level threshold is about 3V—above the TTL guaranteed high-level minimum of 2.8V, but still compatible with CMOS outputs. Do not connect the MAX4501/MAX450 ...

Control system

A control system is a device, or set of devices, that manages, commands, directs or regulates the behavior of other devices or systems. Industrial control systems are used in industrial production for controlling equipment or machines.There are two common classes of control systems, open loop control systems and closed loop control systems. In open loop control systems output is generated based on inputs. In closed loop control systems current output is taken into consideration and corrections are made based on feedback. A closed loop system is also called a feedback control system. The human body is a classic example of feedback systems.
