Hi team,

Do we have a variant that works with 1.8V logic for this?

Thanks,

Luke

The SN74AC595-Q1 (not yet released) has specifications that go down to 1.5 V.

(In practice, you would often need higher voltages for I/O, so you would level-shift the control signals and run the shift register with a higher supply.)

Alternatively, build your own shift register with many flip-flops, e.g., SN74LVC16374A/SN74AUC16374/SN74LVC374A.

Hi Ladisch,

Good news!

Any plans for Non-Q1?

Shoot me an email if you need to take it off-line.

Thanks,

Luke

Hi Luke,

Clemens is not a TI employee he is just a helpful guy who answers on E2E across our product lines :).

We cannot share roadmap on our public E2E forum. You can try to post another on the Logic-Internal forum, or I can email you tomorrow, as today is a US holiday.
