Part Number: SN74LS628 Other Parts Discussed in Thread: SN74LS629 Hello team,
I have a question about connection and voltage conversion of SN74LS628.
Is it possible to directly connect the Z and Y pins of SN74LS628 (DC5V input to VCC) to 3.3V IO …
Part Number: SN74LS628 Hi
1.
Could you check the following connection of RX pin?
Is it correct?
2.
Is it possible to use other than 600ohm?
If yes, what is the impact of changing resistor value?
BestRegards

Hi,
I was able to connect this IC as listed above with the VCC's tied together and the Gnd's tied together. I also set the NC pin to ground, EN to ground, and placed the RNG pin to ground. I used a 50pf capacitor across the CX pins and a 1K variable…
Hi Mirthunraju,
LM567 is a tone decoder, if you are looking for a very low frequency VCO, check to see if below series of part can fix your application.
