The TLP2601 allows high-speed data
transmission at up to approximately 5 MHz.
Data rate of left-side circuit
The high-CTR (current transfer ratio) TLP553
allows operation with low input current (0.5 mA)
and direct driving with a CMOS signal.
Data rate of left-side circuit
When the TLP2200 with a 3-state output is used,
the next-stage logic gate can be actuated
without using a pull-up resistor.
Data rate of left-side circuit
By using the TLP558 which tolerates V
20 V, CMOS logic gates and other components
can be driven without design restrictions on V
