SN74AUCH16374: Question about flip-flop with VLT

Part Number: SN74AUCH16374

Hello team,

My customer asked the any devices which have VLT with the function of SN74AUCH16374.

They want to set the input 1.5V and output 1.8V. Do we have any devices with these feature?

Best Regards,

Austin

Hi Austin,

Can you clarify what you mean by "VLT"? I'm not sure what you mean by this function.

V_IH is 1.17 V, so this is possible.

Please note that the bus-hold inputs, for a high level, have a resistor between the pin and V_CC, so a small current will flow into the 1.5 V device's output.

Hi Albert,

I just said voltage level translator. The customer want to generate different output by the one chip solution.

Austin,

Per Clemens suggestion, if all you are trying to do is do voltage translation from 1.5V to 1.8V, then the device you already have is capable of interpreting a 1.5V input and having the output driven to VCC, since the VIH(min) is 1.17V, 1.5V is a valid input for the device.

Best,
Michael
