SN74AVCH20T245VR

Description This single-bit noninverting bus transceiver uses two separate configurable power-supply rails.
The SN74AVC1T45 is optimized to operate with VccaNcce setat 1.4 V to 3.6 V. It is operational with VccA/NCcB as low as 1.2 V.
The A port is designed to track VCcA- VCcA accepts any supply voltage from 1.2 V to 3.6 V.
The B port is designed to track Vcce. VccB 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.
