About 8× is OK for digital signals.
The termination resistor should match the characteristic impedance of the cable. CAT6 usually has 100 Ω.
A differential transmitter outputs two signals that are inverted from each other. This can be done…
Hi Boyan,
If the requirement is just for an XOR gate, then I might recommend the SN74HCS86-Q1 available in the BQA package. Do we know any timing limitations or output loading concerns?
Pin 3 of the 555 outputs a regular square wave; you can indeed trigger on any edge. You can also replace the 555 with another source (which would be necessary for more than 2 MHz).
The top transceiver is used only as a transmitter; the bottom transceiver…
How have you connected the inputs of the fourth gate? They must never float.
What is the current through D2? Is the voltage at pin 1 ever between V IL and V IH ?
C2 makes the signal edges quite slow. You should use a device with Schmitt-trigger inputs like…
Part Number: SN74HCS00 Other Parts Discussed in Thread: SN74HCS86 ,
I see that there is a SPICE behavioral model for the SN74HCS86. This has been very useful in TINA/P-SPICE simulation.
Would it be possible to get a similar model for the SN74HCS00 NAND…
Part Number: SN74AHC1G86-Q1 Other Parts Discussed in Thread: SN74HCS86-Q1 Hello all,
About the NOR gate SN74AHC1G86QDBVQ1, why in the features TI write Schmitt-Trigger Action at All Inputs Makes the Circuit Tolerant for Slower Input Rise and Fall Time…
Part Number: SN74HC257 Other Parts Discussed in Thread: CD74HC4075 , SN74HC86 , SN74HCS86 , Hi Team
My customer is asking what the HBM value of following 3 devices.
I can't find the info in datasheet.
Could you tell me HBM value for each device and also…
Hey Itoh,
The data sheet covers a handful of devices so its likely one of the others is obsolete as I can still the one you are after is active. However, there are a lot better devices to use here as this one is quite old. I'd recommend the SN74HCS86…
Jejomar,
I would strongly recommend considering the newly released SN74HCS86 for which we have listed the HBM (4kV) and CDM (1.5KV) in the datasheet.
The CD74HC86 is older technology which will not have such high HBM / CDM levels. Please let us know. …
