SN74LVC1T45DCKR

DescriptionThis single-bit noninverting bus transceiver has two independently configurable power rails.
The A port is intended to monitor VCCA. VCCA can accept any supply voltage between 1.65 V and 5.5 V.
The B port is intended to monitor VCCB. VCCB can accept any supply voltage between 1.65 V and 5.5 V. This enables universal low-voltage bidirectional translation between any of the voltage nodes 1.8-V, 2.5-V, 3.3-V, and 5-V.
