Part Number: SN74LS247 I use FPGA to connnect directly with sn74ls247 BCD inputs. FPGA IO is 3.3V level, whereas sn74ls247 is 5V level. Is this a bad design?
Part Number: SN74LS247 Other Parts Discussed in Thread: SN74LVC244A , SN74HC595B Hi Team,
My customer is looking for LED Segment driver, customer use 3bit and customer can accept common cathode or common Anode solution, so can you help recommended one suitable…
Hi Fred,
So we don't have something that can do what you're looking for in just 1 package; however, you can use one of our BCD to 7 Segment display decoders + one of our counters that has an output register built in.
A good combination example…
Other Parts Discussed in Thread: SN74LS90 , SN74LS247 My circuit is just a simple circuit really... What I have done is I've taken a Texas instruments DIP Decade counter SN74LS90 and feed it's output QA,QB,QC,QD to a Texas Instruments BCD to seven segment…
Other Parts Discussed in Thread: SN74LS247 , SN74LS193 I am building a timer that goes from 9 - 0 and then stops. I am using a 555 chip for my timer running at 1 pps. my countdown chip is a SN74LS193. My bcd to seven segment decoder driver is a SN74LS247…
