A digital logic circuit used to store one or more bits. A latch has a data input, a clock input and an output. When the clock input is active, data on the input is "latched" or stored and transfered to the output either immediately or when the clock input goes inactive. The output...
states maintain its output state (on or off) after the input signals which produced the output state change.w It can store the information or the states.w In this chapter, bistable (双稳态双稳态), monostable (单单稳态稳态), and astable (暂态,非稳态暂态,非稳态) logic devices are covered....

The elementary digital gates can be interconnected to form memory elements that can be used to store the previous logic state of an input in a sequential circuit. Figure 2shows the most straightforward digital memory, cross-coupling two NOT circuits N1 and N2. ...

A ladder logic version of the S-R flip-flop is shown here: Relay contact CR3in the ladder diagram takes the place of the old E contact in the S-R latch circuit and is closed only during the short time that both C is closed and time-delay contact TR1is closed. In either case (gate...

a-chip (SoC) technology integrate many distinct components into a single chip. Such components may include microcontrollers, microprocessors, digital signal processing (DSP) cores, memory blocks, and others. Each of these components may include a clock network to synchronize logic and control thereof...
Optimizing Board Space for Discrete LOGIC Designs Using Smallest Package Solutio (Rev. A) The term dual footprint here refers to overlaying two PCB landing pads for two different package configurations. In supply constrained environments, this is a great method to mitigate supply issues for new des...
9 Layout 9.1 Layout Guidelines When using multiple-input and multiple-channel logic devices inputs must not ever be left floating. In many cases, functions or parts of functions of digital logic devices are unused; for example, when only two inputs of a triple-input AND gate are used or ...
