DS90LT012AHMFX/NOPB, also known as DS90LT012A or DS90LT012, is a quad differential line transceiver with bus line fail-safe features from Texas Instruments (TI). It has six integrated drivers and receivers, which work in conjunction with four termination resistors, allowing the user to operate the bus from a single-ended voltage source. This device can be used for a variety of applications and provides a broad range of configurations, making it suitable for various applications.

This device takes 3.3V logic input and provides up to 200 Mbps of data rate transmission. It is designed to support both high speed and low power operation, as it consumes 124 mW while operating at 250 MHz. The maximum output drive capability of this device is 8 mA, with a propagation delay of 390 ps. This device is ideal for applications that require both speed and power savings, such as networking, high speed memory and telecom applications.

The DS90LT012AHMFX/NOPB supports differential signaling on the four bus lines and can detect open or short-circuited bus lines. The reason for this is the four differentially driven bus lines and a fail-safe encoding feature that detects open- or short-circuited bus lines. This encoding ensures data is always transferred at the output even if any input is not connected or corrupted. The device also features an internal pull-resistor for open drain output stages.

The DS90LT012AHMFX/NOPB has flexible control for the two pairs of differential outputs, which can be independently enabled or disabled. If one or both of the outputs are disabled, the device acts as if its input is a logic “1”, regardless of the input supply voltage. In addition, the four termination resistors help reduce the effects of system noise, crosstalk, and reflections.

The DS90LT012AHMFX/NOPB can also be used with flow control. It supports Request-To-Send (RTS) and Clear-To-Send (CTS) signals which enable the device to control data flow between two devices. The received data streams can also be monitored or manipulated when the device is used with a microprocessor or controller. This flexibility makes the DS90LT012AHMFX/NOPB an ideal choice for applications such as serial control and communication, HDD torque control, and other related tasks.

In summary, the DS90LT012AHMFX/NOPB is a highly flexible, low power quad differential line transceiver with bus line fail-safe features. It has six integrated drivers and receivers and four termination resistors, which are used to reduce system noise and reflections. The device supports Request-To-Send and Clear-To-Send signals, which enables it to control data flow between two devices, making it suitable for serial control and communication, HDD torque control and other related tasks.
