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 ...
A set of four high-speed CMOS 20-bit bus switches provides pin-compatible equivalents to existing transistor-transistor-level (TTL) parts. These switches are designed for use in applications such as ...
The 74HC00 data sheet warns that inputs must not be allowed to float because this makes the output indeterminate. Now, that in itself is a good reason, but there is more… In my previous column, we ...
