Hi Sirs,
Sorry to bother you.
We would like use TI SN74LV4051A to replace NXP 74LV4051PW
Our VCC will use on 1.6-1.8v,
The VCC range on NXP is 1-6v, but TI show 2-5.5v.
As TI cross reference there are p2p, right?
So, TI SN74LV4051A is suitable for our application?
Thanks!!
Shu-Chang,
You are correct that the SN74LV4051A is in the same package and pin out as the NXP 74LV4051 device. You are also correct Vcc supply range is specified from 2 V to 5.5 V and the NXP device has a wider range of 1V to 6V. However, the NXP device doesn't specify the Ron at Vcc <2 V as both of these devices Ron will increase as the Vcc decreases.
If you need guaranteed performance with Vdd <2 V I would recommend the TMUX1208 device that is in the same package but it has different pinout.
Thank you,
Adam
