Although rechargeable batteries offer many advantages, they can suffer damage and shortened service lives if they're fully drained of their charge.

We also looked at some latch circuits. This time, I want to look at some actual flip flops–that is circuit elements that hold their state based on some clock signal.

Even though this IC is supposed to work as a latch circuit, it can also be made to function as an R-S flip-flop. No external hardware is required, except for an RC combination for power-on reset.

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 ...

Each circuit is explained, diagramed, annotated, and eventually even demonstrated on a physical breadboard. The only thing you’ve got to do is pick which one you like the most.

Several variations to this circuit exist, but the key in all cases is the addition of a control relay that positively separates the jog function from the latching function, thereby eliminating the ...

The nanotechnology team at Hewlett-Packard has found a way of improving computer power by replacing transistors with the ‘crossbar latch’, which is a bistable-switch latch in the field of molecular ...

Melexis has squeezed a magnetic circuit inside an SMD package to get a end-sensitive Hall effect latch for slim-line motor applications. “We’ve responded to the automotive industry’s demand for more ...
