Hi,
Regarding AND gate chips I have below queries :
1. What is the maximum number of inputs supported by AND gate chips. My requirement is to connect 8 signals (3.3V level) to AND input and generate 1 OUTPUT.
For this requirement what is the best solution you can provide.
2. I just checked on high level and found SN54ALS21A part. Can we use 2 nos of this chip at 3.3V Power ? (use 1 chip to connect all 8 inputs and use another chip to connect 2 OUTPUts of 1st chip to generate 1 OUTPUT). Whether this is the best solution or do you have any better plan?
3. If the plan as mentioned in point 2 is the recommended solution, then whether I can use the chip SN54ALS21A at 3.3V ? If yes then what are the VIH,VIL values for 3.3V power?
Regards,
