2. General
TLP2312 is 5 Mbps high speed photocoupler operated at low supply voltage in the small SO6 package. Since supply voltage of only 2.2 V is needed to operate TLP2312, building another power supply circuit is unnecessary even in using it in a low supply voltage system of 2.5 V LVCMOS level. Therefore, this product contributes to reduce the number of ponents. The low threshold input current (IFLH) of 1.6 mA (max) and the low supply current (IDDL/IDDH) of 0.5 mA (max) at entire operating temperature range of -40 to 125 enables TLP2312 to be driven from a microcontroller directly, and provides 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 mon-mode transient immunity of ±20 kV/µs.
