1. A standard TTL gate performs what logic function for positive logic? 2. If all inputs of a TTL gate are binary 1, the output will be 3. The typical TTL logic levels are: Binary 0= 4. MOS combining both P- and N-channel in series is called 5. The CMOS logic levels are: binary 0 =_______ volts and binary 1 = volts and binary 1 = - volts. volts.

5 Note: Please do not handwritten.

Define a 2-bit demultiplexer to be a circuit whose single input line is steered to one of the four output linesdepending on the state of the two control lines (A, B). Draw its logic diagram (to the gate level) and specify the exactstate of A and B for each output line when that output line is selected.

a) A standard TTL inverter gate is shown in the figure. The supply voltage is 5V. Calculate the output voltage for both logic low and logic high input cases assuming input voltages respectively as 0.11V and 4.2V. Br= 130; BR = 0.24. You can make approximations when needed. Br = IcIs active region; BR = IE/ls inverse active region b) Assume you connect a resistor of 1.8K to the output of the circuit when the output is at logic high. What will be the change in the output voltage? 1302 R3 1.6k2 R, 4k2 Input o T, Output T, V, V. IkQ R,
