12 Power Supply Recommendations

The SN74LVC8T245 device uses two separate configurable power-supply rails, VCCA and VCCB. VCCA accepts any supply voltage from 1.65 V to 5.5 V and VCCB accepts any supply voltage from 1.65 V to 5.5 V. The A port and B port are designed to track VCCA and VCCB respectively allowing for low-voltage bidirectional translation between any of the 1.8-V, 2.5 -V, 3.3-V and 5-V voltage nodes.
