Latches, Flip-Flop and Pewaktu (Timer)
Latches (Definitation)
The output of a latch depends on its current inputs
and on its previous output and its change of state can happen at any time when
its inputs change
· S-R
(Set-Reset) Latch
· Gated
S-R Latch
· Gated D Latch
S-R Latch Active-HIGH Input S-R Latch
S-R Latch Active-LOW Input S-R Latch
Truth Table for Gated S-R Latch
Edge – Triggered Flip-Flops
· Edge
-triggered S-R Flip-Flop
· Edge
-triggered D flip-flop
· Edge
– triggered J-K flip-flop
Asynchronous
Preset and Clear Inputs
The
state of the flip-flop independent of the clock. These preset and clear inputs
must both be kept HIGH for synchronous operation.
