•
This 2-bit non-inverting bus transceiver uses two
separate configurable power-supply rails. The A ports
are designed to track VCCA and accepts any supply
voltage from 1.2 V to 3.6 V. The B ports are designed
to track VCCB and accepts any supply voltage from
1.2 V to 3.6 V. This allows for universal low-voltage
bidirectional translation and level-shifting between
any of the 1.2-V, 1.5-V, 1.8-V, 2.5-V, and 3.3-V
voltage nodes.
