The SN74AVC20T245 is optimized to operate with V

CCA

CCB

set at 1.4 V to 3.6 V. It is operational with

CCA

CCB

as low as 1.2 V. The A port is designed to track V

CCA

. V

CCA

accepts any supply voltage from

1.2 V to 3.6 V. The B port is designed to track V

CCB

. V

CCB

accepts any supply voltage from 1.2 V to 3.6 V. This

allows for universal low-voltage bidirectional translation between any of the 1.2-V, 1.5-V, 1.8-V, 2.5-V, and 3.3-V

voltage nodes.
