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 VTRIP1while 5 and 6 are tied to VTRIP2.The ISETpin has several functions. When taken to V+the outputs are latched and power is completely shut off. Power/speed can be programmed by connecting ISETto V–through an external resistor.ApplicationsTTL/CMOS to ±5V Analog Switch DriveTTL to CMOS (3V to 15V VCC)ECL to CMOS (3V to 15V VCC)Ground Isolation BufferLow Power RS232 Line Receiver
