Level and Edge-Triggering

Level and edge-triggering are two main types of sensitivities of circuits or components to a gating signal, such as a clock.

Level-Triggered

A level-triggered or level sensitive circuit or component can change its output as long as a gating signal, such as a clock signal, is on.

Latches are an example of level sensitive devices.

---

Edge-Triggered

An edge-triggered or edge sensitive circuit or component can change its output only during clock pulse transition. It is notated in circuit diagrams by using a triangle symbol.
 
Edge-triggered circuits or components are either positive-edge triggered or negative-edge triggered depending on whether they change their output on a rising or falling clock edge.

Flip-flops are examples of edge sensitive devices.
