Which of the following IC is the synchronous presettable 4-bit binary counter?
74163 IC Presettable Synchronous 4-Bit Binary Counter IC 74163 is a high speed synchronous modulo-16 binary type counter. The Ic has two type of count enable inputs and a terminal count output which forms a synchronous multistage counter.
What is presettable counter?
It is a PRESETTABLE BINARY UP/DOWN COUNTER, consists of four synchronously clocked D-type flip-flops (with a gating structure to provide T-type flip-flop capability) connected as a counter.
What is presettable synchronous counter?
Presettable synchronous 4-bit binary counter; synchronous reset. The 74HC163; 74HCT163 is a synchronous presettable binary counter with an internal look-head carry. Synchronous operation is provided by having all flip-flops clocked simultaneously on the positive-going edge of the clock (CP).
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 the meaning of presettable?
Presettable meaning Capable of being set in advance. A presettable timer.
How do preset counters work?
A Preset Counter counts until the present value reaches a preset value, and then it activates a control output to operate an output device. The term preset in Preset Counter means that you can set a value in advance.
What do you mean by MOD synchronous counter?
With synchronous counters, all the data bits change synchronously with the application of a clock signal. Modulus Counters, or simply MOD counters, are defined based on the number of states that the counter will sequence through before returning back to its original value.
What is ENT and ENP?
The difference between ENT and ENP is that ENP enables the counter but does not affect RCO. So it enables the counters but does not affect the transition count. You’ll notice (I hope) that for a chain of 162s all the clocks must be tied together.
