The ADM3491ARZ-REEL7 is a high-speed, low-power EIA-485/EIA-422 transceiver module with a driver, transceiver and receiver. It is designed specifically for use in automotive, industrial and communication systems. It is an economical and efficient solution for an RS-485/RS-422 data transmission interface. The module is rated to operate between 0V and 24V and is suitable for operation in applications which require an operating voltage of up to 48V.

The ADM3491ARZ-REEL7 is a half-duplex communication module. It is a three-channel device with two drivers and a receiver. The two drivers are connected to two data pins (D+ and D-). The receiver is connected to a single data pin (RXD). The module is able to read data from the receiver and transmit data from the drivers in the same phase (HS). When transmitting, the data from the drivers is delayed by half a bit time, allowing for a full-duplex communication.

The ADM3491ARZ-REEL7 is designed to handle data rates up to 2Mbps with a maximum of 1.5mA of current consumption at 12V. The module features a low power shutdown mode that can be triggered through the control logic pin. The control logic pin also provides a signal for the status of the module, such as whether it is in a receive mode, transmit mode, or power down state. The module includes a Power-On Reset pin that is used to prevent any data transmission until the module has been properly initialized.

The ADM3491ARZ-REEL7 is particularly well suited for transmitting data over long distances. It is designed to reduce the electromagnetic interference (EMI) and provides a high reduction in the crosstalk between the two data lines. The output driver of the module is able to drive voltages up to 24V. This allows the module to meet the requirements of Class B applications, such as aerospace and automotive. The module also features a differential input and output with a wide common-mode range of up to 30V.

The ADM3491ARZ-REEL7 has a low propagation delay of only 5ns, which gives it an edge over similar devices. This helps to ensure that data is transmitted quickly and accurately from the driver to the receiver over long distances. The module also features a slew rate that is four times faster than others, which helps to reduce the time for data transmission. The module also allows for a high speed of transmission and supports up to 2Mbps of data rate.

The ADM3491ARZ-REEL7 is an ideal device for data transmission in industries such as automotive, industrial and communication. It provides a reliable and efficient solution for data transmission over RS-485/RS-422 networks, while also reducing the total cost of ownership. The module is also suitable for use in applications which require an operating voltage of up to 48V, making it an ideal solution for any application.
