Inverter Gates Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the DCK suffix corresponds to the SC-70-5 package. Confirm the Q1 designation indicates automotive qualification status. Ensure the component meets the specific environmental and electrical requirements for your target application before procurement.

Inverter Gates Selection Notes

Select this component when a single-channel inverter with integrated level shifting is required in space-constrained designs. It is suitable for interfacing between different voltage domains without external translation circuitry. Consider the thermal characteristics and output drive capabilities relative to the load capacitance and trace length in the design.

Inverter Gates Part Context

This part belongs to the SN74LVxTxx family of Texas Instruments logic devices, which are designed for single-supply operation and integrated voltage translation. The LVxT family utilizes enhanced input voltage thresholds to facilitate signal translation across a wide range of supply voltages, making it versatile for mixed-voltage systems.

Inverter Gates FAQ

What is the maximum input voltage tolerance?

The input pins are tolerant of signals up to 5.5V, allowing for down-translation from higher voltage logic levels.

How does the device handle unused inputs?

Unused inputs must not be left floating; they should be terminated to VCC or ground using a pull-up or pull-down resistor to prevent oscillations and excessive power consumption.
