What is 74HC393?
The 74HC393; 74HCT393 is a dual 4-stage binary ripple counter. Each counter features a clock input (nCP), an overriding asynchronous master reset input (nMR) and 4 buffered parallel outputs (nQ0 to nQ3). The counter advances on the HIGH-to-LOW transition of nCP.
How does 74HC93 counter work?
The 74HC93 are 4-bit binary ripple counters. The devices consist of four master-slave flip-flops internally connected to provide a divide-by-two section and a divide-by-eight section. Each section has a separate clock input (CP0 and CP1) to initiate state changes of the counter on the HIGH-to-LOW clock transition.
What is 74LS93?
The 74LS93 is a 4-bit binary counter made of two up-counters. The IC consists of a mode-2 up-counter and a mod-8 up counter. Can be combined as mod-8 counter or divide by 2 or divide by 8 applications. It is built using four JK Flip Flops.
What is 74HC193?
The 74HC193; 74HCT193 is a 4-bit synchronous binary up/down counter. Separate up/down clocks, CPU and CPD respectively, simplify operation. The outputs change state synchronously with the LOW-to-HIGH transition of either clock input. If the CPU clock is pulsed while CPD is held HIGH, the device will count up.
Why are there two clock pins in the 7493 chip?
Pin 2 is a reset pin used to reset the counter in case of any requirement. It’s an active HIGH pin. Pin 3 is the second reset pin used to reset the counter. It’s an active HIGH pin.
How does a binary counter work?
A binary counter is basically a state machine that just cycles through its states for each cycle of a clock signal. The JK flip-flop is considered to be the most universal flip-flop design and can be used as different kinds of flip-flops just by adjusting how the input to the J and K terminals is done.
Which of the following pin is NC pin in IC 74ls93?
Pin 4 is known as NC (no connection) pin which doesn’t have any role in the internal circuit of the IC.
Is 74LS93 is an asynchronous?
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.
How many states have decimal counters?
10 states
Explanation: Decimal counter is also known as 10 stage counter. So, it has 10 states. It is also known as Decade Counter counting from 0 to 9. Explanation: Ripple counters are also called asynchronous counter.
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 do you draw a binary counter?
Binary Counting A binary counter can be constructed from J-K flip-flops by taking the output of one cell to the clock input of the next. The J and K inputs of each flip-flop are set to 1 to produce a toggle at each cycle of the clock input.
What is the difference between IC 74ls90 and 74LS93?
Explanation: The difference between a 7490 and a 7493 is that 7490 is a MOD-10, 7493 is a MOD-16 counter.
Which of the following Pin No is active low pin in IC 74LS93?
The IC consist of multiple mod counters, The Pin 1 is used to give the pulse to mod eight counter. It’s an active LOW pin. Pin 2 is a reset pin used to reset the counter in case of any requirement. It’s an active HIGH pin.
What are two disadvantages to using the 74LS93 integrated circuit?
The disadvantage of using the 74LS93 integrated circuit is that it must start from zero. 3. The circuit shown below is functionally equivalent to the counter simulated in step (2) of the procedure. Why is this implementation a better solution?
