9.3.4.2 Up Translation

Input signals can be up translated using the SN74LV6T17-Q1. The voltage applied at VCC will determine the output voltage and the input thresholds as described in the Recommended Operating Conditions and Electrical Characteristics tables. When connected to a high-impedance input, the output voltage will be approximately VCC in the HIGH state, and 0 V in the LOW state.

The inputs have reduced thresholds that allow for input HIGH state levels which are much lower than standard values. For example, standard CMOS inputs for a device operating at a 5-V supply will have a VIH(MIN) of 3.5 V. For the SN74LV6T17-Q1, VIH(MIN) with a 5-V supply is only 2 V, which would allow for up-translation from a typical 2.5-V to 5-V signals.

As shown in Figure 9-3, ensure that the input signals in the HIGH state are above VIH(MIN) and input signals in the LOW state are lower than VIL(MAX).

Up Translation Combinations are as follows:

  • 1.8-V VCC – Inputs from 1.2 V
  • 2.5-V VCC – Inputs from 1.8 V
  • 3.3-V VCC – Inputs from 1.8 V and 2.5 V
  • 5.0-V VCC – Inputs from 2.5 V and 3.3 V
