74AVC1T45 Dual Supply Transceiver

Diodes Inc. 74AVC1T45 Transceiver is a single bit, dual supply device with 3-state outputs, suitable for transmitting a single logic bit across different voltage domains. The A input/output pin of the 74AVC1T45 is designed to track V_CCA while the B input/output tracks V_CCB. This arrangement allows for universal low-voltage translation between any voltages from 1.2V to 3.6V. The Direction pin (DIR) controls the direction of the 74AVC1T45 Transceiver that has logic threshold voltages related to V_CCA. When a high logic level is applied to DIR the A pin becomes an input and the B pin becomes the output. Conversely, the roles of A and B are reversed when DIR is asserted low.
