Although rechargeable batteries offer many advantages, they can suffer damage and shortened service lives if they're fully drained of their charge. The circuit in Figure 1 shuts off a battery-powered ...

In the previous installment, we talked about why flip flops are such an important part of digital design. We also looked at some latch circuits. This time, I want to look at some actual flip ...

The MC1030 is a clocked dual D-type latch. Any change in the D input will be reflected at the output while the clock is low. The outputs are latched on the clock's ...

This sensitive ON/OFF human interface, non-touch, proximity switch is a fun experiment and may just have some useful applications. A 74HC02 NOR gate acts as a high impedance capacitive sensor. It sets ...

The often-quoted Moore 's Law says that we can expect processors to double in capacity every 18 months. And that has held true. Now computer scientists warn that - without some significant ...
