Other Parts Discussed in Thread: SN74ALVC164245, SN74LVC16T245, SN74LVCH16T245, LSF0108

Is there a 16-bit version of the 74LVC4245A?  It needs to be a surface-mount package.

    Hi Erik ,

    SN74ALVC164245 can be an option for you . It is 16 bits and is available on 48SSOP and 48TSOP packages .

    Thanks for the info.

    The datasheet for the SN74ALVC164245 says there are newer versions available.  Is this part going to be phased out?  Is is better to go with a 16T245 part?

    What is the main difference between these parts (they all seem to be very similar): 

    SN74ALVC164245

    SN74LVC16T245

    SN74LVCH16T245

    I'm looking for a basic 3.3V to 5V and 5V to 3.3V voltage translator.  It looks like all of these parts have individual DIR,OE signals for each byte.

    Hi Erik ,

    The policy of TI is not to phase out devices until the customer keeps buying them . If there are no orders for a long period of time (I think 2 yrs ) then we might consider this for end of life which will be indicated in the website .

    The comparison for 3 of the devices here below : ALVC164245 has dual supplies which operates from 3 to 5.5V and Vcca from 2.3 to 3.6V .recommended.

    Don't you need DIR or OE pins at all ? You can also consider LSF0108 , TXB030x,TXS010x for your applications .They are auto-direction sensing translators.
