Q & A
- What is the primary function of the 74ALVC164245DGGRE4?
The primary function is to act as a 16-bit dual supply translating transceiver, enabling data translation between 3 V and 5 V buses.
- What are the operating voltage ranges for VCC(A) and VCC(B)?
VCC(A) operates from 2.7 V to 3.6 V, and VCC(B) operates from 4.5 V to 5.5 V.
- What is the maximum propagation delay time at 3.3 V?
The maximum propagation delay time (tpd) at 3.3 V is 5.8 ns.
- What is the output drive capability at 3.3 V?
The output drive capability at 3.3 V is ±24 mA.
- How does the direction control input work?
The direction control inputs (1DIR and 2DIR) determine 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 (1OE and 2OE)?
The output enable inputs (1OE and 2OE), when HIGH, disable both nAn and nBn ports by placing them in a high-impedance OFF-state.
- What is the package type and number of pins for this component?
The package type is TSSOP (DGG) with 48 pins.
- What are some common applications for the 74ALVC164245DGGRE4?
Common applications include electronic points of sale, printers and other peripherals, motor drives, wireless and telecom infrastructures, and wearable health and fitness devices.
- What is the operating temperature range for this component?
The operating temperature range is from -40 °C to 85 °C.
- Does the component have any special latch-up performance features?
Yes, the latch-up performance exceeds 250 mA per JESD 17.
