STMicroelectronics Self Powered Digital Input Current Limiter for CLT03-1SC3, CLT03-2Q3 for Programmable Logic

The STMicroelectronics CLT03-2Q3, CLT03-1SC3 Current Limiters are state of the art devices which drastically reduce the power dissipation of digital inputs. The device does not require any external supply as it takes supply from the input signal. The CLT03 series is high side and low side compatible. It can also drive an opto-coupler and LVTTL circuits.
