A 4-bit synchronous counter using JK flip-flops. In a synchronous counter, the clock inputs of the flip-flops are connected, and the common clock simultaneously triggers all flip-flops. Consequently, all of the flip-flops change state at the same time (in parallel). For example, the circuit shown to the right is an ascending (up-counting) four ...
The following is a list of CMOS 4000-series digital logic integrated circuits.In 1968, the original 4000-series was introduced by RCA.Although more recent parts are considerably faster, the 4000 devices operate over a wide power supply range (3V to 18V recommended range for "B" series) and are well suited to unregulated battery powered applications and interfacing with sensitive analogue ...
8-bit addressable latch (Silicon Systems first chip completed) 8-bit parallel output shift register synchronous 4-bit up/down counter. 8288 bus controller for Intel;
In digital electronics, a synchronous circuit is a digital circuit in which the changes in the state of memory elements are synchronized by a clock signal. In a sequential digital logic circuit, data is stored in memory devices called flip-flops or latches. The output of a flip-flop is constant until a pulse is applied to its "clock" input ...
8-bit and 16-bit timers PWM output (some devices have an enhanced PWM peripheral which includes a dead-time generator) Input capture that record a time stamp triggered by a signal edge; Analog comparator; 10 or 12-bit A/D converters, with multiplex of up to 16 channels; 12-bit D/A converters; A variety of serial interfaces, including
This contrasts with serial communication, which conveys only a single bit at a time; this distinction is one way of characterizing a communications link. The basic difference between a parallel and a serial communication channel is the number of electrical conductors used at the physical layer to convey bits. Parallel communication implies more ...
A straight ring counter, also known as a one-hot counter, connects the output of the last shift register to the first shift register input and circulates a single one (or zero) bit around the ring. A twisted ring counter, also called switch-tail ring counter, walking ring counter, Johnson counter, or Möbius counter, connects the complement of ...
