TLP2312 High-Speed Photocoupler Toshiba TLP2312 High-Speed Photocoupler is a 5Mbps high-speed photocoupler operated at a low supply voltage in the small SO6 package. Since a supply voltage of only 2.2V is needed to operate TLP2312, building another power supply circuit is unnecessary even in using it in a low supply voltage system of 2.5V LVCMOS level. Therefore, this product contributes to reducing the number of components. The low threshold input current (IFLH) of 1.6mA (Max.) and the low supply current (IDDL/IDDH) of 0.5mA (Max.) at the entire operating temperature range of -40°C to 125°C enables TLP2312 to be driven from a microcontroller directly and provides an energy saving of systems. The detector has a totem-pole output stage with current sourcing and sinking capabilities. TLP2312 has an internal Faraday shield that provides a guaranteed common-mode transient immunity of ±20kV/µs.
