Frequently Asked Questions
What voltage levels does the SN74AVC4T774PWR support for voltage translation?
The SN74AVC4T774PWR supports VCCA in the range of 1.2V to 3.6V and VCCB in the range of 1.65V to 5.5V. This allows bidirectional voltage translation between common logic levels such as 1.8V, 2.5V, 3.3V, and 5V, making it suitable for mixed-voltage system designs.
What are typical applications for the SN74AVC4T774PWR?
The SN74AVC4T774PWR is typically used in applications requiring logic level translation between different supply voltage domains, such as interfacing a 1.8V microcontroller with 3.3V or 5V peripheral devices. Common use cases include mobile devices, IoT nodes, industrial embedded systems, FPGA I/O buffering, and memory interface circuits.
What package does the SN74AVC4T774PWR come in and what does the 'R' suffix indicate?
The SN74AVC4T774PWR comes in a TSSOP-16 package (16-pin Thin Shrink Small Outline Package). The 'R' suffix in the part number indicates tape-and-reel packaging, which is the standard form for automated PCB assembly and high-volume production.
How is the direction of data flow controlled in the SN74AVC4T774PWR?
The SN74AVC4T774PWR uses a direction (DIR) control pin to determine the data flow direction between the A and B ports. When DIR is high, data flows from A to B; when DIR is low, data flows from B to A. An output enable (OE) pin allows all outputs to be placed in a high-impedance state for bus sharing.
