Q & A
- What is the primary function of the 74ALVC164245DGG112?
The primary function is to act as a 16-bit dual supply translating transceiver, enabling signal translation between 3 V and 5 V buses.
- What are the operating voltage ranges for VCC(A) and VCC(B)?
VCC(A) operates from 2.3 V to 3.6 V, and VCC(B) operates from 4.5 V to 5.5 V.
- How does the direction control input (nDIR) work?
The direction control input (nDIR) determines the direction of 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 (nOE)?
The output enable inputs (nOE) disable the outputs when set to HIGH, putting them into a high-impedance state.
- What is the propagation delay for the 74ALVC164245DGG112?
The propagation delay from nOE to nAn is typically 3.5 ns, with a maximum of 11.5 ns under specified conditions.
- What is the operating temperature range for this component?
The operating temperature range is from -40°C to +85°C.
- Can the 74ALVC164245DGG112 be used as multiple transceivers?
