Inverter 74 LS04 has following specifications I0H max = - 0.4 mA, I0L max = 8 mA, IIH max = 20 μA, IIL max = 0.1 mA
The fan out of this inverter is -
A 4 bit ripple counter starts in 0000 state. When the counter reads 0010 the number of clock pulses which have occurred is
-
The number FF in hexadecimal system is equivalent to number __________ in decimal system.
-
The inputs A, B, C of the given figure are applied to a 3 input NOR gate. The output is
-
Assertion (A): XOR gate is not universal gate.
Reason (R): It is not possible to realize any Boolean function using XOR gates only.
-
A 2 bit BCD D/A converter is a weighted resistor type with ER = 1V, R = 1 MΩ and Rf = 10KΩ then Resolution in percent and volt is __________ .

= 80 Fan out in high state = 
Hence fan out is smaller of two values ie., 20.
where d is Resolution in volts.
