Q & A
- What is the 74ALVC164245DGG653 used for?
The 74ALVC164245DGG653 is a 16-bit dual supply translating transceiver used for voltage-level translation between 3 V and 5 V buses in mixed voltage environments.
- What are the supply voltage ranges for VCC(A) and VCC(B)?
VCC(A) ranges from 2.3 V to 3.6 V, and VCC(B) ranges from 3.0 V to 5.5 V, with VCC(B) ≥ VCC(A).
- How does the direction control work?
The direction control inputs (1DIR and 2DIR) determine the direction of the data flow. When nDIR is HIGH, data flows from nAn ports to nBn ports, and when nDIR is LOW, data flows from nBn ports to nAn ports.
- What is the purpose of the output enable inputs?
The output enable inputs (1OE and 2OE) control the output states. When these inputs are HIGH, the outputs are in a high-impedance state, and when they are LOW, the outputs are enabled.
- What is the operating temperature range of the 74ALVC164245DGG653?
The device operates from -40°C to +125°C.
- Can the 74ALVC164245DGG653 be used as multiple transceivers?
Yes, it can be used as two 8-bit transceivers or one 16-bit transceiver.
- What are the typical applications of the 74ALVC164245DGG653?
It is commonly used in voltage-level translation, embedded systems, industrial automation, and consumer electronics.
- What are the input voltage levels for HIGH and LOW states?
For VCC(A) = 3.0 V to 3.6 V, VIH is 2.0 V and VIL is 0.7 V. For VCC(B) = 4.5 V to 5.5 V, VIH is 2.0 V and VIL is 0.8 V.
- How does the device handle input transition rise and fall rates?
The input transition rise and fall rates vary depending on the supply voltage, but typically range from 0 to 20 ns/V.
- What is the significance of the 3-state bus compatible outputs?
The 3-state bus compatible outputs allow the device to interface with other 3-state compatible devices, enabling or disabling the outputs as needed.
