The DS3486N/NOPB is an advanced, feature-rich serial data transceiver. Utilizing differential signaling, it offers an improved signal-to-noise ratio compared to single-ended transmission. With its low VIO and low power dissipation, DS3486N/NOPB is well suited for use in combination with other digital ICs and peripheral devices in various communication systems.

The DS3486N/NOPB is a low-voltage, bi-directional, differential bus transmitter/receiver. It is designed to provide cost effective, low voltage solutions for balanced I/O solutions. The device consists of two drivers for transmitting data and two receivers for receiving data.

Designed for general-purpose applications, the device supports a wide range of data protocols. The transmitter and receiver circuits operate independently, allowing the device to be configured for full-duplex, half-duplex, or simplex operation. In addition, the part features a low-voltage differential signaling (LVDS) optimized output. This allows the part to operate with very low power consumption, making it well suited for portable or battery-operated systems.

DS3486N/NOPB has a wide range of applications in the field of interface drivers, receivers and transceivers. It is commonly used as a bridge between standard digital logic and analog circuits, providing a reliable interface for digital and analog signals. Its extended temperature range (–40°C to +85°C) makes it well adapted for automotive applications.

DS3486N/NOPB is capable of transmit and receive data up to a rate of 250 Mbps. The transmitter and receiver use an internal enable/disable function that is used to enable or disable the device. Using the enable/disable feature allows the device to be used in partial duplex or simplex operation. This feature also allows the device to be used as a bus transceiver with variable bus loading.

DS3486N/NOPB features two differently sized receiver inputs. A small active-low data-valid input indicates when valid data is present, and a larger active-low receiver input assert to indicate that data has been received. The output enable pins control whether the transmitter drives the output or the receiver receives data. The transmitter has active high output enable control for driving outputs high, and the receiver has active low output enable control for driving outputs low.

The DS3486N/NOPB also integrates an on-off charge pump. This provides a stable power-rail supply of 1.2V to reduce power consumption and promote reliable operation of the transceiver at lower power voltages. The on-off charge pump design allows current to be only drawn when the device is enabled.

The device also features advanced fault detection and protection features. The active-low fault detect pins are designed to indicate if a fault exists in the serial link. The fault detect pins can also be used to diagnose computer conditions during power up and other times when the system’s operation may be questionable.

In conclusion, the DS3486N/NOPB is an ideal choice for industrial and communication applications, due to its flexibility and low power consumption. It is an ideal device for connecting digital and analog signals, providing enhanced reliability and improved signal-to-noise ratio. With its integrated fault protection, it provides superior protection for the bus line. The on-off charge pump provides a stable power-rail, and the receiver and transmitter are independently enabled and disabled, allowing for full-duplex, half-duplex and simplex operation.
