The DS3696N/NOPB is a dual differential transceiver designed for use in digital and communications systems requiring differential bus (EIA/TIA-485) level shifting from low voltage/low voltage to higher voltage/lower voltage. Designed for low power consumption, the DS3696N/NOPB provides an interface between two independent voltage levels.The DS3696N/NOPB includes two differential transmitters that are capable of driving up to 256 unit loads. The input logic levels are compatible with both TTL and CMOS logic families. The differential receivers provide levels of fanout capability of up to twenty-four (24) TTL/CMOS inputs.The DS3696N/NOPB offers a number of advantages over other transceivers. One of the most prominent advantages is the device’s low power consumption. This is achieved by the device’s power-down feature, which allows it to consume less than 1mA of current when powered down. In addition, the DS3696N/NOPB features built-in low-noise input and output buffers that provide a high degree of isolation from external noise sources. Furthermore, the device’s internal ESD protection mechanism eliminates the need for additional external components. The DS3696N/NOPB is a reliable and versatile transceiver, which can be used in many applications including applications requiring differential transmitter/receiver devices for EIA/TIA-485 serial communications and applications requiring bus buffering at multiple logic levels. With its low power consumption and integrated low-noise input and output buffers, it is an ideal solution for those looking for an efficient and reliable interface between two independent voltage levels. To better understand the application fields and working principle of the DS3696N/NOPB, an overview of its main components and operation is provided in the following sections.The DS3696N/NOPB consists of two independent differential transceivers, each containing two differential antennas, a driver, and a receiver. The antennae each consist of a pair of complementary metal oxide semiconductors (CMOS) transistors. The driver is composed of a pair of complementary N-Channel MOSFETs and a pair of P-Channel MOSFETs. The receiver is made up of a differential pair of CMOS transistors.The transceivers are enabled by a single control pin. This pin is used to set the operating state of the transceiver. In the active state, the driver circuit is activated and the receivers are in the standby mode. In the standby mode, both the driver circuit and receivers are disabled and the device consumes less than 1mA of current. The transceiver can switch between the two voltage levels (V_OH and V_OL) by setting the proper logic control for each level. When the logic is low (V_OL), the device is in the receive mode and the differential input is detected. When the logic is high (V_OH), the device is in the transmit mode and the differential transmit is activated. The device can also be put into the standby mode for power conservation. The DS3696N/NOPB features extremely accurate output levels and very low EMI emissions. It is also equipped with built-in thermal protection and input and output protection diodes for added reliability and stability. The DS3696N/NOPB is ideally suited for applications requiring differential transmitter/receiver devices (for example, EIA/TIA-485 serial communications) and bus buffering at multiple logic levels. The device is available in a variety of packages and is RoHS compliant.In conclusion, the DS3696N/NOPB is an ideal solution for interfacing two independent voltage levels and is well-suited to various applications such as EIA/TIA-485 serial communications and applications requiring bus buffering at multiple logic levels. With its low power consumption, reliable operation, and ESD protection, it is sure to provide an efficient and reliable interface for any application.
