SN65LBC173N

The SN65LBC173N is a 3.3V, 16-pin low-power, 5 Mbps, half-duplex transceiver that incorporates proprietary linear transmission technology. It can be used in a wide variety of applications such as digital communication, safety, automotive and industrial. It is suitable for multi-point, full-duplex communication, as well as in classic point-to-point applications.

The SN65LBC173N transceiver operates in two modes, one for transmitting data and another for receiving data. The transceiver is able to receive and transmit at speeds up to 5Mbps in either mode, allowing the user to switch between the two modes seamlessly.

In transmit mode, the SN65LBC173N uses the current source circuitry to drive the bus line with either a logic ‘1’ or a logic 0, with a guaranteed minimum output drive current of 16mA across the bus line. The other features in transmit mode are a selectable output slew rate of either 25% or 75% and also a programmable output enable for each channel which allows for several different combinations of power saving and enable/disable options.

In receive mode, the SN65LBC173N uses its high-impedance common-mode sensing circuit to detect incoming logic levels. This sensing range extends from -400mV to +800mV around the common mode voltage, allowing it to accurately detect incoming logic ‘1’ and ‘0’ levels within this voltage range. Also in receive mode, the bus input provides power to the receiver so there is no need to provide power to the device when transmitting or receiving data.

The SN65LBC173N transceiver chip is also designed with additional features like a low-skew output enable for improving transmission repeatability, and a differential logic output for reducing EMI. These features make it ideal for use in automotive and industrial applications, where data transmission rate and accuracy are essential.

Overall, the SN65LBC173N is a reliable, low-power transceiver which makes it ideal for use in a wide variety of applications. Its combination of features makes it suitable for both low-data rate point-to-point transmissions, as well as high-speed full-duplex communication. The ability to switch between transmit and receive modes quickly and easily makes it an optimal choice for applications needing reliable and efficient data transfer.
