TLP291-4
1. Applications
• Programmable Logic Controllers (PLCs) • Switching Power Supplies • Simplex/Multiplex Data Transmission
2. General
The Toshiba TLP291-4 consists of phototransistors optically coupled to an infrared LED. The TLP291-4 Photocoupler is housed in the very small and thin SO16 package. Since the TLP291-4 is guaranteed over a wide operating temperature range (Ta = -55 to 110 ), it is suitable for high-density surface mount applications such as programmable controllers.
