SCLS744D December 2013 – February 2024 SN74LV1T126
PRODUCTION DATA
Input signals can be up translated using the SN74LV1T126. 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 SN74LV1T126, 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.
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) as shown in Figure 8-4.
