Can I share a single pull resistor on multiple enable pins to save space?

Electrical Engineering Asked on January 6, 2022

I am using this Schmidt trigger IC SN74HCS125 which has 4 channels

I would like to save some board space by hopefully using only one resistor to pull down the enable pins of each channel. I do not plan to connect those enable pins to anything else as I want them to be always enabled.

I have not done this before since what I have been doing since now was individually giving them their own resistor. Just intuitively speaking it should work, but there might be caveats that I am not aware of. Is doing this perfectly fine?

One Answer

The unused inputs can be directly connected to ground (or supply voltage). It even reads in the datasheet.
