The LTC487CN#PBF is an intrinsically safe, galvanically-isolated, 2-wires, opto-coupler driver suitable for industrial hazardous industries. The device can be used in different applications such as process control, motion control, pressure and level sensing, PLCs and safety monitoring systems. It is characterized by its high speed (15MB/s) and its high powered output (1A).

The interface circuit provides an opto-coupler driver with improved performance and advanced features. It is capable of operating up to 1A peak current and up to 15MB/s data rate. The LTC487CN#PBF uses its own voltage regulator that provides up to 5V off-state voltage. It is designed to be integrated on the printed circuit board and is suitable for industrial signal transceiver, receiver and driver applications. It supports both TTL and LVDS signal levels.

The working principle of the LTC487CN#PBF is based on the principle of isolating DC (positive and negative) signals. It uses a transmission gate to switch the signal on or off with a logic voltage level. Incorporated into the device is an opto-coupler that provides electrical isolation between theisolated device and the circuit. The opto-coupler allows the signal to be transferred between the two circuits without any parasitic currents. In addition, the device provides a selectable slew rate control which reduces the necessary speed to output a reliable signal.

There are two types of output stage: the open drain type and the universal type. The open drain type provides a single common output that is connected to the voltage supply or to ground. On the other hand, the universal output type provides a positive and negative logic output. Both types have an open drain conduction period and are capable of providing up to 15MHz of data rate.

The LTC487CN#PBF is an ideal choice for a wide range of applications. It provides an efficient and reliable means of high-speed data signaling and isolating DC. It can also be used as an interface between standalone process devices and industrial device networks. Its fast rise and fall times, combined with its high powered output, makes it suitable for a range of industrial and hazardous area applications. Additionally, its low power consumption and universal outputs make it useful in both digital and analog applications.
