Working principle of SN75185PWR

SN75185PWR is an open-drain differential line receiver which is a type of bidirectional level shifter for connecting two-line systems. It has two outputs (OUT1 and OUT2) and two inputs (IN1 and IN2). The differential amplifier takes two signals as input and amplifies them, then output them as two voltage-level signals. The two inputs are amplified and then compared against a reference voltage to determine whether the output should be a 1 or a 0. In data communication, two lines (IN1 and IN2) travel in opposite direction and these lines must contain the same type of signal in order for the differential receiver to work properly. When one input (IN1) is at a high level and the other (IN2) is at a low level, the open-drain differential receiver will output a high signal. The output is converted to a logic level signal by a logic gate. The logic gate pulls down the line when it is outputting a "low" level. When the line is pulled down, it is said to be in the "off" state. The open-drain differential receiver can also be configured as a switch, where it is used to control the switching of signals.

In summary, SN75185PWR is an open-drain differential line receiver which is a type of bidirectional line receiver for connecting two-line systems. It is widely used in communication networks, industrial automation and automotive applications. It takes two signals as input and amplifies them, then outputs them as two voltage-level signals and can be configured as a switch.
