Detailed Pin Configuration

The ISL84051IB has a total of 8 pins:

1. VCCA: Positive supply voltage for the A-side logic.
2. GND: Ground reference.
3. A1: A-side input/output pin 1.
4. A2: A-side input/output pin 2.
5. OE: Output enable pin.
6. B2: B-side input/output pin 2.
7. B1: B-side input/output pin 1.
8. VCCB: Positive supply voltage for the B-side logic.

Functional Features

• Bidirectional voltage level translation between A-side and B-side logic.
• Push-pull or open-drain operation modes selectable through the OE pin.
• Automatic direction sensing eliminates the need for direction control signals.
• High-speed data transmission with minimal propagation delay.

Advantages and Disadvantages

Advantages

• Wide operating voltage range allows compatibility with various logic families.
• ESD protection safeguards against electrostatic discharge events.
• Low power consumption minimizes energy usage.
• High-speed operation enables fast data transfer.

Disadvantages
