Could you please provide us with the current lifecycle status (e.g., Active…
Part Number: SN74LS47 I ordered 10 new SN74LS47 to finish a clock. I have a working 60 second count up but when I replace an old SN74LS47 with one of the new 10 that I bought the seven segment counter stops working. I can see that the input to the IC…
Part Number: SN74LS47 Other Parts Discussed in Thread: MSP430FR2000 HI Sirs,
Sorry to bother you.
We are survey Binary to 7-segment and find SN74LS47
We would like to show that 10 is A, 11 is B...
Looks 47 is not suitable solution, right??
So…
Other Parts Discussed in Thread: SN74LS47 It would be convenient to revise the datasheet of the sn74ls47. Students go into unnecessary complications because the technical data there still mentions limitations that have long been overcome, like for example…
Other Parts Discussed in Thread: SN74LS47 Hi all!!
I am using SN74LS47 to connect 12 seven segment displays to LM4F232H5QD MCU, I am planning to use BCD to SEVEN SEGMENT DIVIDER SN74LS47. As per the datasheet 46A, 47A and LS47 will be used for common…
Hello Manzar,
I'm moving this post to the Logic Forum as it is the SN74LS47 device that you are having trouble with. However you should provide what logic is being input to the SN74LS47 as well as the output given vs. output expected if you want to…
Hello Bruno,
Use to have that problem back in the days is the SN74LS47. Adding 10k pull down resistors to the outputs fixed the problem of ghosting. You may want to go with the highest resistor value to reduce current drain. Depending on your layout…
