To replace SN65LBC174N instead of SN75ALS194N?

Other Parts Discussed in Thread: SN65LBC174, SN75ALS194


Current SN75ALS194N is used now,

Can I use N65LBC174N (pin to pin compatible) instead of SN75ALS194N?

in other words,

Is it possible to replace SN65LBC174N instead of SN75ALS194N without any H/W changing?


  • Hi Eric,

    From comparing the datasheets, it looks like you can change to the SN65LBC174 from the SN75ALS194 without any hardware changes. The only differences I see are in the timing characteristics. Ths LBC174 is a little bit slower than the ALS194, so you will need to make sure that it still works at the speeds you are operating at. 

    Let me know if you have any more questions!
