This 8-bit noninverting bus transceiver uses two separate configurable power-supply rails. The SN74LVC8T245

is optimized to operate with V

. V

CCB

accepts any supply

voltage from 1.65 V to 5.5 V. This allows for universal low-voltage bidirectional translation between any of the

1.8-V, 2.5-V, 3.3-V, and 5.5-V voltage nodes.
