We have received some suggestions from another engineer for third party components. Obviously, anything suggested will need to be vetted by you for your application as Microchip can not support or verify third party products. However, here are the suggestions:

A lot matters on the choice of vcc
http://www.nxp.com/documents/data_sh...LVCH16373A.pdf - is a 3 v part
http://www.ti.com/lit/ds/symlink/sn74ahc16373.pdf is slower, but supports 5v
