Although simple in concept, interfacing digital levels between different logic families usually requires many parts and appreciable board space. Other applications that require some form of level shifting of the output swing have solutions just as complicated. A logic to CMOS analog switch (Figure 10.1) is just one example where a level shift must occur. A new device, the LTC1045, solves this and other level shift related problems conveniently. The LTC1045 is a hex level translator with a linear comparator on the front end. A latch and three-state output buffer ...
