SN65C1167ENS

SN65C1167ENS is a high-speed, high-performance EIA-485/RS-485 differential line receiver. It features an extended operating temperature range to ensure reliable operation in the widest range of temperatures. The SN65C1167ENS is intended for applications where data rates up to 10 Mbps are required. Its low power consumption and high data rate make it suitable for low-power, high-speed data acquisition and automation systems and applications.

The SN65C1167ENS is a receiver designed to operate from data-grade, standard-grade, or speech-grade twisted-pair telecom lines, and from coaxial cable. It has an input commonly referred to as an "A", and an output commonly referred to as a "B". When the pair of lines is in use, an analog signal is present on the "A" line, and a reference signal is present on the "B" line. The SN65C1167ENS can operate either in a "normal" mode or in a "bus-powered" mode.

In normal mode, the SN65C1167ENS will interpret the input signals and convert them into EIA-485/RS-485 compliant outputs. The data rate is determined by the slew rate of the input signal, which is controlled by the switching speed of the SN65C1167ENS. In bus-powered mode, the SN65C1167ENS will only interpret signals with a maximum rate of 10 Mbps, and the slew rate of the input signal is not limited by the switching speed of the receiver.

The internal circuitry of the SN65C1167ENS includes an input bias control circuit, an I_B/Q control circuit, and a differential amplifier. The input bias control circuit regulates the bias current for the differential amplifier. The I_B/Q control circuit is used to set the receiver\'s operating characteristic of the data rate. When the input signal reaches a certain threshold, the I_B/Q is adjusted to correctly interpret the signal. Finally, the differential amplifier is used to return the input data signal to a digital signal which can be further processed by other components in the system.

The SN65C1167ENS operates by converting an input signal into a digital signal output. This allows it to accurately translate a signal over a wide range of data rates. The SN65C1167ENS is an ideal solution for applications requiring multiple input signals over a single twisted pair line. It is suitable for small or large systems, with up to 32 nodes on a single bus. Additionally, the device has low power consumption, making it suitable for battery-powered systems.

In conclusion, the SN65C1167ENS is designed to provide a reliable and high-speed data connection over twisted-pair and coaxial cables. It is capable of operating up to 10 Mbps and supports up to 32 nodes on a single bus. The device is suitable for low-power and high-speed data acquisition and automation systems and applications. It is also suitable for applications requiring multiple input signals over a single twisted pair line.
