TISN74AVC4T245
Overview
The SN74AVC4T245 is a 4-bit non-inverting bus transceiver that uses two separate configurable power-supply rails to translate voltages between 1.2V and 3.6V. It features a direction-control pin for managing data flow between the A and B ports, making it ideal for interfacing low-voltage processors with higher-voltage peripherals or legacy logic.
Why Choose This Part
This transceiver supports VCC isolation, ensuring that if either VCC input is at ground, all outputs enter a high-impedance state to prevent backflow. It includes Ioff circuitry for partial-power-down mode operation and provides robust ESD protection and latch-up performance exceeding 100mA.
Applications
Key Specifications
Getting Started
When designing with the SN74AVC4T245, ensure the VCCA and VCCB rails are properly decoupled with 0.1uF capacitors placed close to the pins. Since this is a direction-controlled translator, the DIR pin must be driven by the host controller to define the data path. For evaluation, the device is available in standard SOIC and VQFN packages compatible with common breakout boards and SMT prototyping workflows.
