74LVC1T45 Description
The 74LVC1T45 is a single-bit, dual-supply transceiver with tri-state outputs suitable for transmitting a single logic bit across different voltage domains. The A input/output pin is designed to track VCCA while the B input/output tracks VCCB. This arrangement allows for universal low-voltage translation between any voltages from 1.65V to 5.5V.
