SN74AVC4T774 – 4-Bit Voltage Level Translator, Bi-Directional

📝 Product Description

The SN74AVC4T774PWR is a compact, high-performance 4-bit dual-supply bus transceiver with configurable direction control — ideal for voltage-level translation in multi-voltage systems such as open-source mining rigs, custom PCBs, Raspberry Pi add-ons, or Bitaxe miner extensions.

Built by Texas Instruments, this IC provides seamless voltage conversion between two logic levels (e.g., 1.2V to 3.3V, or 1.8V to 5V), making it essential for DIY electronics projects where microcontrollers and sensors operate at different voltage domains.

Perfect for developers working with crypto mining hardware, embedded systems, or advanced prototyping where signal integrity and power efficiency are critical.

⚙️ Key Features

• 🔁 Bi-Directional Logic Level Translation
  Seamlessly translates signals between different voltage levels using A/B direction control.

• ⚡ Dual-Supply Operation
  Supports independent VCCA and VCCB rails (1.2V–3.6V & 1.65V–5.5V), ideal for mixed-voltage designs.

• 📶 4-Bit Wide Parallel Bus
  Translates up to four data lines simultaneously — great for compact layouts.

• 🔒 Built-in Power-Off Protection
  Prevents current backflow when the device is powered down.

• 🚀 High-Speed, Low-Power Design
  Supports >100Mbps data rates with minimal propagation delay.

• 📦 TSSOP-14 Package
  Surface-mountable and easy to integrate into custom PCB designs.
