SN74LVC8T245: Need similar device

Go Bravos

Team,

Do you know if another TI voltage translator transceiver that has slower rise and fall time? Do you think weaker (< 24mA) output drive may help reduce overshoot/undershoot? Are there any voltage translator that may have built-in series resistors?

Thank you.

AVC/AXC family devices have slightly weaker output drivers (but go only up to 3.3 V).

If you do not need direction switching, you might be able to use AUP1T or LV1T/LV4T family devices.

Hi Brad,

Here is a link to our parametric search with the internal damping resistor filtered:

Weaker drivers will have less undershoot/overshoot, but no all translators go up to 5 V so it would help to know what voltages you have to work with for the supply. External series resistors can also be used to help dampen the overshoot/undershoot.
