The SN75154NSR is a quadruple line driver and receiver pair that is used to expand the number of signal lines required for serial communication between multiple devices. This type of device is usually used in the automotive and industrial control applications. The advantages of this type of device include its capability to provide high speed data transmissions, low power requirements, and excellent electromagnetic compatibility with other circuits in the system.

The SN75154NSR is a non-inverting, four-channel line driver and receiver pair with separate output enable (OE-A and OE-B) and input enable (IE-A and IE-B) pins. The driver is optimized for low-voltage operation and can drive up to four TTL loads on the outputs. The receiver portion is powered by the same supply voltage as the driver and offers excellent signal integrity. It includes a Schmitt Trigger input for noise immunity, even in the presence of slow logic switching.

The SN75154NSR application field are used to expand or multiplex the number of signal lines necessary in conventional buses with limited number of lines by adding additional pairs of drivers and receivers. This type of application is most commonly used in automotive and industrial control applications, where more than two devices need to communicate and share information. The device is also used to extend the reach of serial communication systems, especially if the system contains multiple devices.

The working principle of the SN75154NSR is simple. The driver portion has two output enable pins (OE-A and OE-B) that control the output state. When either of these pins is active, the corresponding output is enabled and the signal is sent to the associated receiver. The input enable pins (IE-A and IE-B) control the state of the receiver, allowing the signal from the corresponding driver to be read. The Schmitt Trigger logic ensures that the signal is properly received, even in the presence of noise and slow logic switching.

The SN75154NSR is a robust and reliable device that is used to expand or multiplex the number of signal lines necessary in conventional buses with limited line numbers. It has low power requirements, excellent signal integrity and electromagnetic compatibility, and the Schmitt Trigger input ensures noise immunity, even with slow logic switching. The SN75154NSR is ideal for applications that require multiple devices to communicate and share data, as well as for extending the reach of serial communication systems.
