TCA4311A: LTC4301 p2p replaceable?

Part Number: TCA4311A
Other Parts Discussed in Thread: TCA4311

Hi Team,

It seems LTC4301 and TCA4311A have same pin out, are they p2p drop-in replaceable?

 I cannot tell from the datasheet of their difference, but RnD said we cannot replace them due to some reason.

Anyone knows the major differences? Thanks.

Andrew

    Hi Andrew,

    I'm not aware of any important differences between these devices that would prevent TCA4311A from being a drop-in replacement, but our team will review this in detail and get back to you on Monday.

    Hey Andrew,

    It seems the biggest difference between these two devices is that TCA4311 utilizes a rise time accelerator whereas the LTC4301 does not.

    The only other thing I see is LTC4301 uses a low signal on/CS to enable their device while the TCA4311 uses a logic high to enable the device so it is not exactly a direct replacement due to that logic; though it does seem to be an easy fix.

    Thanks,
