Open Collector and Other Types of Gates

Question 1

What is one application of a gate with an open collector output?

Answer 1

the wired AND connection

Question 2

When all legs of the AND gate except one are off, what is the current sink capability and AND condition?

Answer 2

current sink capability is minimum, while the AND condition is false

Question 3

What is Schmidt trigger capability?

Answer 3

a comparator circuit with hysteresis implemented by applying positive feedback to the noninverting input of a comparator or differential amplifier.

Question 4

What is the 74LS132 an example of?

Answer 4

a circuit with Schmidt trigger capability

Question 5

What is hysteresis?

Answer 5

the phenomenon in which the value of a physical property lags behind changes in the effect causing it, as for instance when magnetic induction lags behind the magnetizing force.

Question 6

input voltage rsises from L to H and then falls from H to L, where the gain is very high so that a small voltage delta across either threshold forces a full H-L transition of the output

Answer 6

Schmidt trigger capability

Question 7

Schmidt trigger converts a waveform to a two level what?

Answer 7

H, L waveform

Question 8

positive feedback in the circuit causes rapid H to L and L to H transitions of the output when thresholds are crossed by a what?

Answer 8

a slewing waveform
