Part Number: CD4541B I'm using the CD4541B as a digital timer and have selected Rtc and Ctc for a 21 second count with pins 12 and 13 tied high. I do NOT want the powering on of the device to change the output state. I only want the output to change state…
Part Number: CD4541B Other Parts Discussed in Thread: SN74LVC1G123 I am using this part in Digital Timer Application as it is recommended in the datasheet on page 5. My VDD is +5V+/-5% and at low end alternative part from ON Semi (MC14541) stops working…
Part Number: CD4541B Dear Ti Expert,
Is any difference in terms of functionality between CD4541B-E3 and CD4541B-E4. Can we use CD4541B-E3 as a replacement for CD4541B-E4? The reason I am asking this is because our design normal use CD4541B-E4 for production…
Part Number: CD4541B Other Parts Discussed in Thread: SN74LVC1G14 , SN74HCT74 , CD74HC4040 , CD74HC163 I am contracting with a customer and need your help with their circuit that uses the CD4541B. The frequency we measure on the bench does not equate…
Part Number: CD4541B Other Parts Discussed in Thread: CD4017B Hi,
I'm using the CD4541B to create an automotive timer. I know the limitations of the clock and am planning on using an external oscillator for accuracy. However, to verify the functionality…
Part Number: CD4541B First question: am I correct that the state of the Q output is undefined at power-on if the chip is turned on with AR pulled HIGH? And I will take it the state will stay undefined until a Manual Reset pulse is given in that case?…
Part Number: CD4541B On page 5 of the specification, it is stated "A setup time equal to the width of the one-shot output is required immediately following initial power up, during which time the output will be high."
If I understand this correctly…
Part Number: CD4541B Hi Team,
My Customer would like to know if the datasheet of CD4541B has an error on page 4 on the Transition Time Parameter? Since this Parameter has two tTHLs on the table (picture below).
Looking forward to your inputs.

Hey Dylan,
For my design, I will use a supply of 10 V, oscillator frequency of ~10 kHz with an output of ~1.22 Hz (10 kHz / 8192 = 1.22 Hz).
First I select the required capacitor with the given equations on the front page of the datasheet:
…
Part Number: CD4541B Other Parts Discussed in Thread: CD4047B , CD4011B The quiescent current is rated at 10uA max for 10V.
It is not clear to me if that rating is with the oscillator running or not.
I ask because my timer circuit is drawing 270uA…
