What is a 7493 counter?
The 74LS93 is a up-counter built using four JK flip-flops. The CP1 and Q0 forms a mod-2 counter using a single flip-flop and the CP0 with Q1, Q2 and Q3 with three flip-flops forms the mod-8 counter. The IC is commonly used by combining mod-2 and mod-8 to form a mod-16 up-counter.
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.
What is the difference between 7490 and 7493?
Explanation: The difference between a 7490 and a 7493 is that 7490 is a MOD-10, 7493 is a MOD-16 counter. Thus, 7490 traverses 10 states and 7493 traverses 16 states.
How many flip-flops are there in binary counter IC 7493?
4 flip-flops
Integrated circuits (ICs) 7493 and 7490. These are “classic” IC counters circuits containing 4 flip-flops. Structurally, 7493 acts as a binary 4-bit counter and it can count up to 15, hence M cascaded 7493 can count from 0 to 16M-1.
What is a binary counter?
A binary counter is a hardware circuit that is made out of a series of flip-flops. The output of one flip-flop is sent to the input of the next flip-flop in the series. A binary counter can be either asynchronous or synchronous, depending on how the flip-flops are connected together.
What is the use of IC 7493?
The 7493 digital IC is a 4-bit binary counter. It can count from 0 to 15 based on a digital clock applied to the appropriate input pin. The 7493 4-bit Binary Counter IC pinout is shown in Figure 13.
How does a 4-bit counter work?
A 4-bit Synchronous up counter start to count from 0 (0000 in binary) and increment or count upwards to 15 (1111 in binary) and then start new counting cycle by getting reset. Its operating frequency is much higher than the same range Asynchronous counter.

Which pins need to be connected together on a 7493 to make a mod 12 counter?
A MOD-12 counter will have 12-states. Thus, it is clear from the diagram shown below: 12 & 1 are clear pins, 11 & 3 are clock pins, 8 & 2 are input for 7493 FF.
What is 4-bit ripple counter?
4-Bit Ripple Counter. This circuit is a 4-bit binary ripple counter. All the JK flip-flops are configured to toggle their state on a downward transition of their clock input, and the output of each flip-flop is fed into the next flip-flop’s clock.
How many of states are there in a 4-bit counter?
16 states
Therefore, in a 4-bit counter, the total number of states = 24 = 16 states.
How to operate the 7493 IC as a 4-bit counter?
The 7493 IC can be operate as a 3-bit counter using input B and flip-flops QB, QC and QD. It can operate as a 4-bit counter using input A if output QA is connected to input B. Therefore, to operate the circuit as a 4-bit counter, it is necessary to have an external connection between pin 12 and pin 1.
74LS93 or SN74LS93 is a 4-bit binary counter. Counters have a major role in every electronics device. The output of the counters can be used in multiple devices as pulse counting or for generating interrupts, etc. Counters come up in two form Asynchronous and Synchronous counters.
What is a 74l93 binary counter?
The whole IC gives the output 4 bits which counts from 0 to 15 in binary. This is compatible with any microcontroller or TTL based devices. It comes in multiple packages such as DIP, SMD with all 14-pins. The 74L93 binary counter comes up with internal protection from high-speed termination.
How can ICIC type 7493 be used as a BCD counter?
IC type 7493 can be operated as a BCD counter by making the external connections shown below. Outputs QB and QD are connected to the two reset inputs, Rl and R2 When both RI and R2 equal to 1, all four cells in the counter clear to irrespective of the input clock.
