DS90LV032ATMTC/NOPB

The DS90LV032ATMTC/NOPB is an advanced low voltage non-inverting bus transceiver supporting data transmission between two nodes running at 0.9 volts. This device is largely used in the application field of various industrial control systems, such as audio and video controllers, battery chargers and other automotive systems. It is designed to provide a reliable and accurate data transmission between two nodes with different power supply and logic levels. The device also offers an internal clamping diode and an I2C bus interface.

The DS90LV032ATMTC/NOPB has multiple gain levels providing data transfer rate ranges from 1 Mbps to 8 Mbps. The transceiver includes two bi-directional channels that can switch between two different power supply or logic levels. It also utilizes a pair of complementary output drivers to support a low serial output as well as a differential line. This device also offers a high input capacitance allowing fast switching from high to low and from low to high logic levels.

The working principle of the DS90LV032ATMTC/NOPB relies on the basic non-inverting bus transceiver. It provides two output channels which operate independent from each other. Each output is driven by a complementary pair of transistors in open-collector mode. The output transistors are connected to the output of buffer inverters, connecting them to either power supply or logic levels. To provide an additional output voltage level, a clamping diode is connected between the output of buffer inverters and power supply.

The DS90LV032ATMTC/NOPB outputs are driven by logic signals and are not subject to any external control. To ensure that the devices inputs and outputs remain at the correct logic level, the device is provided with a low voltage level shifter circuit. This ensures that the signal level of the input logic signals are converted to a level compatible with the device.

In order to ensure accurate signal transmission, the DS90LV032ATMTC/NOPB can be configured to operate in either open-collector or inverted open-collector mode. In open-collector mode, the low level output is not affected by the input signal, regardless of its logic state. In inverted open-collector mode, the feedback logic value is clamped to either high or low logic levels, depending on the logic state of the input signal. In this mode, the output signal is also high and low logic levels, with high and low logic levels, as determined by the input signal.

The I2C bus interface provided with this transceiver allows other devices to be connected directly to the transceiver and allows data to be transferred between devices. The I2C bus protocol allows devices to transfer data at different clock frequencies, allowing for more efficient and faster data transfer.

In summary, the DS90LV032ATMTC/NOPB is a reliable and advanced low voltage non-inverting bus transceiver that is used in a variety of applications in industrial control systems, such as audio and video controllers and battery chargers. Its multiple gain levels and two independent output channels allow for reliable and accurate data transmission between two nodes with different power supply and logic levels. The I2C bus interface of the device also allows for efficient data transfer between different devices.
