Product Details

The LTC1045 is a hex level translator manufactured using an enhanced LTCMOS silicon gate process. It consists of six high speed comparators with output latches and three-state capability. Each comparator’s plus input is brought out separately. The minus inputs of comparators 1 to 4 are tied to VTRIP1 while 5 and 6 are tied to VTRIP2.

The ISET pin has several functions. When taken to V+ the outputs are latched and power is completely shut off. Power/speed can be programmed by connecting ISET to V through an external resistor.

Applications

  • TTL/CMOS to ±5V Analog Switch Drive
  • TTL to CMOS (3V to 15V VCC)
  • ECL to CMOS (3V to 15V VCC)
  • Ground Isolation Buffer
  • Low Power RS232 Line Receiver
