The 74LVC1T45GS,132 is a 1-bit dual-supply bidirectional level-shifting transceiver introduced by Nexperia, housed in an ultra-small XSON-6 (1x1mm) surface-mount package. This device supports bidirectional level shifting between any voltage nodes from 1.2V to 5.5V, making it suitable for interfacing common logic levels such as 1.2V, 1.8V, 2.5V, 3.3V, and 5.0V.
The data transfer direction is controlled by the DIR pin: when DIR is high, data is transferred from port A to port B; when DIR is low, data is transferred from port B to port A.
