The SN74GTLP21395PWG4 is an integrated logic translator and level shifter for a wide range of applications. It offers the capability to transfer data between voltage levels of two (VCC1 and VCC2) different logic families without ever changing the signal state. This makes it ideal for communication across a variety of architectures and platforms. The key features of this versatile component include:

Features

• Two power supply ranges: VCC1=1.8V to 5.5V; VCC2=2.3V to 5.5V
• 5-bit bidirectional translator
• Output capable of driving up to 25 mA
• Flow-through pinout facilitates board layout
• Maximum operating temperature up to 125°C
• Available in an 8-pin WSON package
• Cascadable to 32-, 64- and 128-bit designs

Applications

The SN74GTLP21395PWG4 is useful in a wide range of applications because of its ability to reliably and seamlessly transfer data between two different power supplies. It is well suited for communication between two or more logic families. Common applications include:

• Embedded controller and I/O interfacing
• Communication between microcontroller and memory devices
• Networking interfaces
• Communication between peripherals and controllers

Working Principle

The SN74GTLP21395PWG4 operates as a bidirectional, five-bit level translator. It is two channels wide and accepts five-bit inputs on each side. Communications between the two voltage levels can occur in both directions. The device can operate at supply voltages ranging between 1.8V and 5.5V. The output drivers are capable of driving up to 25 mA.

The SN74GTLP21395PWG4 uses a patented side biasing mechanism that translates data between the two input levels without changing the state of the signals. This allows seamless data transmission between different voltage levels at the same time. A flow-through pinout design is employed to reduce package size and minimize board layout area.
