LTC1045 Datasheet PDF - Linear Technology

DESCRIPTION
The LTC®1045 is a hex level translator manufactured using Linear Technology’s enhanced LTCMOSTM 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.
