8 Bit Level conversion module


It is a logical level shifter module.
This 8-bit noninverting translator uses two separate configurable power-supply rails.
The A port is designed to track VCCA. VCCA accepts any supply voltage from 3.6 V.
The B port is designed to track VCCB. VCCB accepts any supply voltage from 5.5 V.
This allows for low-voltage bidirectional translation between any of the 2.5-V, 3.3-V, and 5-V voltage nodes. When the output-enable (OE) input is low, all outputs are placed in the high-impedance state.
To ensure the high-impedance state during power up or power down, OE should be tied to GND through a pulldown resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver.
