How many numbers can be counted by a 4-bit binary counter?
A block of 4 bits is called a nibble (half a byte!) and it can hold a maximum number of 1111 = 15 in decimal. Many counting circuits work with blocks of 4 bits because this number of bits is required to count up to 9 in decimal. (The maximum number with 3 bits is only 7).
What is a 4-bit binary counter?
The SN74HC163 is a 4-bit binary counter. This mode of operation eliminates the output counting spikes normally associated with synchronous (ripple-clock) counters. A buffered clock (CLK) input triggers the four flip-flops on the rising (positive-going) edge of the clock waveform.

How many flip flops are needed for a 4-bit counter?
4 Flip Flops
This means that to design a 4-bit counter we need 4 Flip Flops. The counter also has a reset pin that enables it to enter an all-zero state i.e. the output of the counter is ‘0’ if the reset is ‘1’ irrespective of the clock and the current state of the flip flops.
Which one is a 4-bit binary ripple counter *?
Which one is a 4-bit binary ripple counter? Explanation: IC 7493 is a 4-bit binary ripple counter. It is a MOD-16 counter with 24 = 16 states. Explanation: IC 7493 consist of 4 J-K master-slave flip-flop.
What is 4-bit ripple counter?
In 4-bit ripple counter, n value is 4 so, 4 JK flip flops are used and the counter can count up to 16 pulses. Below the circuit diagram and timing diagram are given along with the truth table. 4 bit Ripple Counter using JK Flip Flop 4 bit Ripple Counter Timing Diagram.
What does a 4-bit counter do?
4-bit Synchronous Counter Waveform Timing Diagram Because this 4-bit synchronous counter counts sequentially on every clock pulse the resulting outputs count upwards from 0 ( 0000 ) to 15 ( 1111 ). Therefore, this type of counter is also known as a 4-bit Synchronous Up Counter.

How does a 4-bit binary ripple counter work?
A binary ripple counter consists of a series connection of complementing flip-flops (T or JK type), with the output of each flip-flop connected to the Clock Pulse input of the next higher-order flip-flop. The diagram of a 4-bit binary ripple counter is shown in Fig. below. All J and K inputs are equal to 1.
What is 3 bit ripple counter?
The number of states that a counter owns is known as its mod (modulo) number. Hence a 3-bit counter is a mod-8 counter. A mod-n counter may also be described as a divide-by-n counter.
