Description

The LTC1145A/LTC1146A provide 2500VRMS (1minute) or 3000VRMS (1 second) of input to output isolation for TTL digital/CMOS signals. The LTC1145/LTC1146 are intended for less stringent applications and are rated for 500VRMS. Unlike opto-isolators, the input current is a mere 70mA for the LTC1146 which can handle frequencies up to 20kHz. The faster LTC1145 will handle frequencies up to 200kHz while only drawing 700mA.

The output signal of LTC1145A/LTC1146A  is in phase with the input and swings between GND2 and VCC providing a TTL/CMOS compatible signal without any pull-up resistors. An on-chip noise filter helps prevent glitches and data errors at the output, and a pin is provided for synchronizing the output signal to an external system clock.
