10.5 TIMERS/COUNTERS/LATCHES


There are some devices and concepts that are temporal/sequential (time based) or sequential. This means that they keep track of events over time, as opposed to conditional logic that decides based on instantaneous conditions.



Controls that have states or time dependence will require temporal controls (also known as sequential).

Some devices that are temporal are:

Flip-Flops - These can be latched on or off.
Latches - Will stay on until reset (Similar to flip-flops)
Counters - Keeps a count of events
Timers - Allows inputs and outputs to be delayed or prolonged be a known amount
