9.3.4.1 Down Translation

Signals can be translated down using the SN74LV6T17. The voltage applied at the 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. As shown in Figure 9-2, ensure that the input signals in the HIGH state are between VIH(MIN) and 5.5 V, and input signals in the LOW state are lower than VIL(MAX).

As shown in Figure 9-3 for example, the standard CMOS inputs for devices operating at 5.0 V, 3.3 V or 2.5 V can be down-translated to match 1.8 V CMOS signals when operating from 1.8-V VCC.

Down Translation Combinations are as follows:

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