Electronics II Flashcard

Front

What does "IC" stand for in electronics?

Back

Integrated Circuit

Front

Why is the 555 timer called "555"?

Back

It uses three 5kΩ resistors internally

Front

How many pins does a 555 timer IC have?

Back

8

Front

What is inside a 555 timer IC?

Back

Flip-flops, comparators, resistors, and transistors

Front

In monostable mode, the 555 timer produces a pulse when:

Back

Triggered by an external pulse

Front

What is the function of the discharge pin (Pin 7) in a 555 timer?

Back

Discharges the timing capacitor

Front

In astable mode, the 555 timer:

Back

Continuously oscillates without external trigger

Front

What determines the output frequency in an astable 555 circuit?

Back

The resistor and capacitor values

Front

In a 555 monostable circuit, increasing the capacitor value will:

Back

Increase the output pulse duration

Front

What is the typical voltage range of a 555 timer?

Back

4.5V to 15V
