Compared to other logic families, the LVxT family is the most well-rounded and universal in terms of specifications. The LVxT family of devices combines a reduced input threshold voltage with a wide supply range, allowing for up or down voltage translation with only one power rail. The family has overvoltage-tolerant inputs that allow down translation from up to 5.5 V down to the supply voltage, which can be as low as 1.6 V. The reduced input thresholds allow for up-translation from inputs as low as 2.03 V up to 5-V outputs. See the list below for a summary of common voltage nodes and translation combinations supported.
| 1.8-V Supply | 2.5-V Supply | 3.3-V Supply | 5.0-V Supply |
|
1.2 V → 1.8 V 1.8 V → 1.8 V 2.5 V → 1.8 V 3.3 V → 1.8 V 5.0 V → 1.8 V |
1.8 V → 2.5 V 2.5 V → 2.5 V 3.3 V → 2.5 V 5.0 V → 2.5 V |
1.8 V → 3.3 V 2.5 V → 3.3 V 3.3 V → 3.3 V 5.0 V → 3.3 V |
2.5 V → 5.0 V 3.3 V → 5.0 V 5.0 V → 5.0 V |
The LVxT family includes many common logic gates such as AND, NAND, OR, NOR, XOR, and XNOR functions. We also offer configurable gates that provide the greatest flexibility. See our full portfolio of translating gates here.
Because only one supply is required for operation, the LVxT family of logic can be used to reduce the number of supply rails required in some systems.
The LVxT family are available in the surface mount DBV (SOT-23) and DCK (SC70) packages and replace both a logic function and voltage translator reducing BOM count and overall solution size.
Unlike open-drain translators, no external resistors are required for voltage translation.
All LVxT devices support up to 5.5-V input signals independent of supply voltage allowing for simple down-translation.
Inputs can be at different voltages, allowing for logic using signals from different voltage domains.
