I can seem to find specifics on that. One thing I did find is that with 3. Why does this work? R3 was moved to the right just to clear up some clutter.
Embedded Systems and Microcontrollers. Historical anecdotes on my other uses for RS latches. Dec 11, 6. Dec 15, 8. Thanks a ton for everyone’s help!!
Is the enable line capable of effectively “resetting” the latches? Comments like these are one of the many reasons for which I regret skipping all the theory in the electronic classes and being in the first line only when there was the risk to toast stuff.
In this scenario a common reset channel on the IC would help maximizing the numbers of available latches in the same footprint and make the circuit more elegant and simple. Please note I’ve never tested it, yet I think it will work. Dec 10, 2. I want to keep it flexible, both capability and power-usage wise and this requires balance.
Email Required, but never shown. I thought the IC could handle 10mA. I remember seeing info in the CD datasheet on the CD? I see a small error from moving parts around. Thanks for the reply.

On processors such as the Atmel AVR that power is in the single microamp region – the clock doesn’t need to be running.

Once you correct that, can you go through exactly what the circuit is supposed to do? Sourcing it could be really troublesome.
daatsheet Basically just have a short signal to trigger the reset instead of a continuous high signal as would be from the LED output. Can’t yet wrap my head around applying a D or JK that way.

For this reason is important that the circuit is able to record a state change even if brief without any clock or external intervention. Dec 15, 9. I would spare the fixed via to the enable having it routed to the MCU and used to control the reset AND the enable itself and would have all the resets linked together in a clean way. Post as a guest Name.
Their datasheet comment says the MCU would be sleeping, before you posted your ‘answer’. I’m still trying to get used to those truth tables.
datsaheet You might way to use the common enable in the CD to implement the solution you’re looking for. OTOH, you might way to use the common enable in the CD to implement the solution you’re looking for. The reason why I was looking at concentrating everything in Hex Latches instead of Quad Latches was to reduce the IC count and, with dqtasheet, to have a cleaner design of the traces.
