Interface - Drivers, Receivers, Transceivers is a programming technology widely used in the real-world applications. SN751701PSR is one of the widely used transceiver ICs due to its good performance. This article will discuss the SN751701PSR\'s applications field and its working principle.

In terms of function, SN751701PSR is a half-duplex transceiver with 9-bit receiver, 8-bit transmitter and clock available. It is mainly used for two-way serial communication applications. For instance, this transceiver can be used in the data bus of industrial automation systems. Moreover, computer networks, telecommunication protocols, and instrument systems also benefit from this transceiver.

In terms of working principle, SN751701PSR is driven by voltage-level logic signal. When power is applied to the chip, the chip will enter the working status automatically.

When transmitting data, the signal from input pins will first pass through the logic circuits. Then the signal will be converted to TTL levels and it will be transmitted to the bus. At the same time, the clock signal will be transmitted through the clock out pin. The clock signal will be used in the receiving module to ensure the proper data reception.

When receiving data, voltage levels from the bus will be conditioned by charge pumps and ESD clamping circuits. Then the signal will be received by the logic circuits, which will amplify and clean up the signal. Finally, the signal will be converted to TTL logic levels, and it will be output through the output pins.

In summary, SN751701PSR is a specialize transceiver IC with 9-bit receiver, 8-bit transmitter and clock available. It is mainly used for two-way serial communication applications and it is driven by voltage-level logic signals. When transmitting data, the signal from input pins will be converted to TTL levels and it will be transmitted to the bus. When receiving data, voltage levels from the bus will be conditioned by charge pumps and ESD clamping circuits, and then the signal will be output through the output pins.
