SN74AXC2T245-Q1: 2input 1output level translator

Part Number: SN74AXC2T245-Q1
Other Parts Discussed in Thread: SN74LV4T32-Q1, SN74LVC1G32-Q1

Hello Expert,

Our customer is looking forward following device.

Input1: 1.8V 50MHz
Input2: 3.3V 10MHz
Output: 1.8V

We could found 1:1 level shifter or OR type input logic as like as SN74LV4T32-Q1.
However, we'd like to switch 2type of different input level input as like as mux.

Is there such a device?

If there isn't it, we are planning to add switch before level translator but we'd like to optimize BOM count.

Best regards,
Kazuki Kurmaochi

Modern logic families have overvoltage-tolerant inputs. You can just use the SN74LVC1G32-Q1.

Clemens,

As I explained, we need level translator and switch IC in 1 package,
Your device is just or and it doesn't satisfy this requirement.

Is there any device which can satisfy their requirement by 1 IC?

Best regards,

What exactly do you mean with "switch"? Please specify all possible inputs and the resulting outputs.

Hello Kazuki,

Are you asking for a level translator and an OR gate in one package? If so we don't have such device in our portfolio.

Regards,

Josh

Hello Josh,

Thank you for your support.

We discussed about this socket with customer and they finally decided to won't use this socket in their system.
So I'd like to close this thread.
