SN74LV541A: If there is a fixed Voh/Vol part, with other specs similar to SN74LV541A?

Hi team,

I want to check If there is a fixed Voh/Vol part, with other specs similar to SN74LV541A?

My customer is looking for a buffer to support 3.3V to 5V supply voltage, but they want to the Voh and Vol to be fixed. For example, 2V for high and 0.8V for low, can you help check whether we have such portfolio? Thanks!

Regards,

Xiaoying

    3.3 V happens to be the TTL output voltage, so you can use buffers with TTL-compatible inputs like the SN74AHCT541 or SN74LV541AT.

    There are single-supply level shifters with lowered switching thresholds at the inputs like the SN74LV4T125. They do not have more than 4 channels, and with a 5 V supply, they behave the same as TTL-compatible inputs.

    There are dual-supply level shifters like the TXU0104 or SN74LXC8T245.
