The LS7082N1 CMOS quandrature clock converter is designed to interface between incremental encoders and counting devices by converting the encoder quadrature outputs into directional up/down clocks or ...

It turns out that if you run standard CMOS at 3.3 V, the logic levels are the same as TTL running at 5 V. In my previous column, we took a look at the 74HCT series of CMOS parts with TTL-compatible ...
