TLP2161
1. Applications
• Factory Networking
• High-Speed Digital Interfacing for Instrumentation and Control Devices
• I/O Interface Boards
2. General
The Toshiba TLP2161 consists of a high-output infrared LED coupled with a high-speed photo-diode-transistor
chip. It is housed in the SO8 package. It has two circuits built into a single SO8 package, which can reduce the
mounting area.
This photocoupler guarantees operation at up to 125 and on supplies from 2.7 V to 5.5 V. Since TLP2161 has
guaranteed 2 mA low supply current (ICCL/ICCH), and 1.6 mA (Ta = 125 ) low threshold input current(IFHL), it
contributes to energy saving of devices. It can drive directly from a microcomputer for a low input current.
The TLP2161 has an internal Faraday shield that provides a guaranteed common-mode transient immunity of
±20 kV/µs.
