63 fast TTL interface It is surprising how often TTL ICs are asked to perform a difficult (if not impossible) task. It is, of course, gratifying to know that experimenters have so much confidence in ...

The logic on-off function allows the user to shut off the converter’s output using a simple TTL logic signal or mechanical switch, and avoids having to turn off the DC input bus. This feature is ...

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 ...

This is a TTL logic probe which, instead of the usual LED to indicate the logic states, uses a seven-segment Minitron or LED display to indicate `H` for a high or `1` state and ` L` for a low or `O` ...

You can’t leave unused inputs floating, but you might not want to connect them to a power or ground rail either. Digital engineers learned long ago that they should not leave unused inputs unconnected ...

EPC has announced a laser driver that integrates a 40V 10A GaN power switch with a differential input gate driver. Called EPC21603, its inputs are LVDS (low-voltage differential signalling) compatible ...
