Other Parts Discussed in Thread: TS3A5018, SN74CBTLV3257

Hi,

In one of our design we are using SN74CBT3257CPWR , can we give VCC as 1.8v and 1.8v IO signals.

Does this work without any issue.

If not please suggest me with same footprint should operate at 1.8v 2:1 mux demux 8 channels

Hi Hariharapandian,

Instead of the CBT which is not recommended for 1.8V operation , you could consider TS3A5018 which is qualified for 1.8V Vcc operation and can pass 1.8V I/O signals.
You could consider sn74CBTLV3257 to work at 2.3V and operate 1.8v I/O as well.
would either of this work ?
