MC145406N,602 Application Field and Working Principle

The MC145406N,602 is an integrated circuit used in many consumer and industrial devices. It is a dual, low-power EIA/TIA-595- and JEDEC-compliant transceiver and can be configured as an RS232-compatible line driver and/or receiver. It is packaged in a standard 8-pin SOIC package and can be used in a variety of applications, ranging from handheld consumer electronics to industrial control systems.

Applications

The MC145406N,602 is ideal for low-power applications where both line drivers and receivers are needed and multiplex data streams must be generated. This integrated circuit can be used in point-to-point, bus, and multi-drop communication systems. It is suitable for applications such as rate-compensated PCM data links, RS232 interprocessor communication, and EIA/TIA-595 communication. The integrated circuit can also be used in systems requiring full-duplex and half-duplex communication.

Working Principle

The MC145406N,602 is a dual transceiver that supports both line drivers and receivers. The line driver portion of the circuit is powered by a 5V supply, while the receiver portion is powered by a 3.3V supply. Two separate differential receivers are included in the circuit, with one being enabled by the RD pin, and the other being enabled by the RE pin. The line drivers are enabled by the SE (Serial Enable) and DE (Data Enable) pins, respectively. The SE pin enables the line driver to transmit all data, while the DE pin enables the line driver to transmit only the data that is specified by the Data line. The line receivers are enabled by the RE (Receiver Enable) pin.When enabled, the line driver transmits the data from the Data line to the Receiver Output pin. On the receiver side, data is received from the Receiver Input pin, amplified, and then output to the Data line. This allows data to be transmitted between devices without the need for additional line receivers or level converters.

Conclusion

The MC145406N,602 is a dual, low-power EIA/TIA-595- and JEDEC-compliant transceiver. It is ideal for low-power applications where both line drivers and receivers are needed, such as rate-compensated PCM data links, RS232 interprocessor communication, and EIA/TIA-595 communication. The integrated circuit is a cost-effective solution for providing reliable data transfer between different devices.
