Subsection 08 Integrated circuits Flashcards
3 binary counters in cascade, what is the division?
- each serial counter changes its state once every 2 clock pulses, so 3 serial counters divides by 2x2x2 = 8
A device which converts serial to parallel and parallel to serial arithmetic functions is a?
Shift register
A parallel register, reads each BIT to be stored?
Simultaneously
A program counter and shift register is called?
Special purpose registers
A serial-IN/ Parallel-OUT register would take its outputs from?
The Q outputs from all the flip-flops
A shift register is used to?
Move and retain data
A typical characteristic of a CMOS is?
Low power dissipation
An ALU is an example of
MSI
An encoder changes data from?
One format to another
An example of a small size integrated circuit would be?
An ALU
An RS Flip=flop with Q at 1 is said to be?
SET
Data is converted from serial to parallel and parallel to serial by a?
Shift register
If 3 binary counters are connected in casade method to form a frequency divider, what is the division factor which will be applied to the signal?
8
In a J-K flip flop when J=0, K=1 and Q=1 what will Q be?
0 on the next clock pulse
In a master slave, negative edge triggered JK flip flop, both inputs are connected to logic 1. The output will change state when?
The trailing edge of the clock pulse is applied
In an RS flip flop, output is one, this means?
It is set
On an IC, Pin 1 is to the left of the notch, which way are the pins numbered?
Anticlockwise
Operation of a frequency counter is such that it changes the incoming waveform to a?
Standard square wave
Synchronous counters are those where all the flip flops are?
Clocked simultaneously
The pins on an op-amp are numbered
Anticlockwise
Very large scale integrated ( VLSI) means the number of gates in a single IC is upto?
10,000
What is the device used to convert binary coded decimal into supplies for a seven segment digital display?
Decoder
What will a 4 BIT binary counter read starting from zero after 64 clock pulses?
0000
When 4 binary serial counters are connected in cascade for frequency division, what division factor is required?
16
When a JK flip flop is used as a memory device, what type of memory would it be?
Volatile
Which of the following registers is not directly accessed by the user?
Data buffer
Why are MOSFET’s used in watches and calculators?
They are very small/ low power consumption
With a J-K flip flop which is the output set?
Q=1
Within a 3 Bit frequency cascade, division is to?
8
