Question

I did Problem #4 a. 2V(min) 15V(max) b. 100mA c. 10mA
Let me know if this is correct, and slso I need Problem #4
The is about TLC555, refer to datasheet website www.ti.com Problem a. The reset and trigger pins on the 555-timer IC are said to be active low. What does this mean? b. If V 15V, what voltage, as seen by the threshold pin, must the capacitor reach before the output of the 555-timer returns to zero, and the capacitor can discharge? c.An LED circuit is connected to a 555-timer such that the timer is sinking the current through the LED circuit. During what point of the output signal, either high or low, is the LED illuminated? Explain your answer. Problem 4 Refer to the datasheet for the TLC555 timer IC to answer the following questions. The TLCS55 timer is a variant of the LM555 timer discussed in class. a. What is the minimum supply voltage required for the TLC555 to operate? b. What is the typical sink current for the TLCS55? C. What is the typical source current for the TLC555

Explanation / Answer

A)Single-Supply Operation From 2 V to 15 V

mIN SUPPLY VOLTAGE=2V

MAX SUPPLY VOLTAGE =15V

B)

Sink current =100mA

C)

SOURCE CURRENT=10mA

The advantage of the TLC555-Q1 is that it exhibits greatly reduced supply-current spikes during output
transitions. Although the CMOS output is capable of sinking over 100 mA and sourcing over 10 mA, the main
reason the TLC555-Q1 is able to have low current spikes is due to its edge rates. This minimizes the need for
the large decoupling capacitors required by the NE555.
