voltage divider 3.3 2.5

Hello all!
I want to conevert a ttl level signal to 3.3 or 2.5 V.
I was wondering if a basic voltage divider could do the job?

Is it really necessary a smart Ic for this conversion?

Best regards!

How fast does your converter need to be, and how much load current does it need to drive?

My converter needs to ensure a min 20MHz freq and load form 5-10mA!

your best call is a digital switch - see NC7SZ384 for a single gate or P5C3244 for 8 switches. They are very good as level translators.

Hope it helps.
