Part Number: NA555 Other Parts Discussed in Thread: TLC555 Hi Support Team.
In the Qualification Summary, the results of ESD-HBM and CDM are described as "See data sheet". However, the datasheet does not show the results of ESD.
Please tell…
Part Number: NA555 Other Parts Discussed in Thread: TLC555 , NE555 Hi team,
There is questions need to confirm
Q1: the customer want to know the supply current about the NA555. Here is how they use:Under normal circumstances, PIN 3 TRIG inputs high level…
Part Number: NA555 Hello,
My customer is trying to realize astable timer operation with NA555.
Because they want to realize about 50% duty, they selected 200 ohm for RA (RB=1.5K ~ 3.4Kohm, C=0.1uF).
But some datasheet parameters are specified under RA…
Part Number: NA555 Other Parts Discussed in Thread: TLC555 Hi Team,
I want to generate 1.2s(+/-20%) negative single pulse using NA555. Do you have any example design such the one shot pulse generator using 555 timer?
If possible, I want to use positive…
Part Number: NA555 Hi team,
According to the datasheet, the minimum working voltage range of NA555DR is 4.5-16V, but customer have measured 5PCS samples, and the minimum working voltage is about 2.2V Compared with the competing products currently used…
Part Number: SA555 Other Parts Discussed in Thread: SE555 , , NE555 , NA555 Hi team,
Could you tell what makes NA555, NE555, SE555 and SA555's operating tempreraure ranges different?
NA555, NE555, SE555 and SA555 look similar but customer wants to …
Part Number: NA555 Hi team,
The output waveform is abnormal, related to the pulldown/pullup resistance added at the output pin
At the output, add a pull-down resistance of 5.1k. The output waveform has a step:
change to pullup resistor of 1k to the output…
Part Number: NA555 I want to use this component to design an accumulation timer. Do you have any reference to the schematic? The total time is six months and then manually reset.
Hi Zeng,
I recommend using the TLC3555-Q1 instead of the SE556 for this application considering your intended operating frequency of 1MHz or higher.
For information on building a PWM generator, see the 7.2.2 Pulse-Width Modulation section of the TLC555-Q1 datasheet…
