    can AM29F040B-55JF work with TTL logic levels

    MuA_4743186

      Hi,

       

      could anyone help with the acceptable voltage levels for AM29F040B-55JF. I think this part is obsolete now. But need this details. Vcc is 5V but the /CS, /RD, /WR & Addr lines are at 3.3V. Datasheet specifies DC characteristics for both TTL/NMOS & CMOS. But its not clear whether the same device can work on both levels (or) we need to choose a different part number. IF its same device, is there any HW configuration to be done to accept TTL logic signals.

       

      Thanks & Regards
