Part Number: SN74HCS08-Q1 Hi Team,
my customer asks if the layout suggestion in datasheet is a good practice, since the pads reach underneath the chip.
Thanks

Part Number: SN74HCS08 Hi Expert,
We are proposing the SN74HCS08DR to replace the SN74HC08DR.
Pls confirm whether is true of Overlap of switching threshold of datasheet.
Examples for 4.5Vcc :
Positive switching threshold is 1.7V ~3.15V
Negative switching…
Part Number: SN74AHCT08 Other Parts Discussed in Thread: SN74HCS08 Tool/software: Hi, I am using this quad AND gate as shown below. In the application, the VCC pin is tied to ground and the GND pin is tied to -3.45V as I'm using negative logic. My…
1. All modern logic families have a little bit of hysteresis at the inputs, but it's only 100 mV or so. Its only purpose is to work around the inductance of the pins and the bond wires, so there is no hysteresis that is guaranteed to be available for…
Part Number: SN74HCS08-Q1 Hello,
I have one question regarding the specification for 3,3V power supply for the SN74HCS08-Q1 AND Gatter.
There is no particular information how the positive switching threshold would be for 3,3V +-3%. So do you have measured…
Part Number: SN74LVC1G07 Other Parts Discussed in Thread: SN74HCS21 , SN74HCS08 , SN74LVC08A Hi
I have a question about SN74LVC1G07.
VCC(3V3_PEX) voltage level with impact output (Y) voltage level?
If Tri_REG_PG use 3.3V is ok? thanks!

That is not possible with a mux.
You could use AND gates (e.g., SN74HCS08 or SN74HCS21) to combine the four RX signals. But this will not work if two nodes try to communicate at the same time.
You need Schmitt-trigger inputs to support slow edges.
AND gates with Schmitt-trigger inputs exist only with four channels (SN74HCS08) or as a configurable gate (SN74LVC1G97, SN74AUP1G97).
