74LVC8T245PW
Overview
The 74LVC8T245PW is an 8-bit, dual-supply translating transceiver designed for bidirectional voltage level translation between 1.2V and 5.5V rails. It features 3-state outputs and utilizes two separate power supply pins (VCC(A) and VCC(B)) to allow independent logic levels on each side of the device.
Why Choose This Part
This transceiver supports an ultra-wide supply range from 1.2V to 5.5V, providing flexibility for almost any logic node. The I-off circuitry disables the outputs when the device is powered down, preventing damaging backflow current in partial power-down applications.
Applications
Key Specifications
Getting Started
Ensure that VCC(A) is tied to the logic level of the first bus and VCC(B) to the second; the direction is controlled by the DIR pin. Place 0.1uF decoupling capacitors close to both VCC pins to manage switching noise during high-speed transitions.
