Description

The TLP291-4 is a highly integrated, 4-channel transistor output optocoupler housed in a compact and thin SOIC-16 surface-mount package. Each channel comprises a high-efficiency Gallium Arsenide (GaAs) infrared-emitting diode optically coupled to a silicon phototransistor.

Designed for high-density PCB layouts, the TLP291-4 is perfect for space-constrained applications like hybrid ICs and Programmable Logic Controllers (PLCs). It features a wide operating temperature range (-55°C to 110°C) and provides reliable electrical isolation, making it a robust solution for signal transmission between systems with different voltage potentials.
