Overview
The 74AVC4T774PWJ is a 4-bit, dual supply translating transceiver produced by Nexperia USA Inc. This component enables bidirectional level translation between two different voltage domains, making it highly versatile for various electronic designs. It features eight 1-bit input-output ports (An and Bn), four direction control inputs (DIR1, DIR2, DIR3, and DIR4), and an output enable input (OE). The device supports dual supply pins (VCC(A) and VCC(B)) that can operate within a wide voltage range from 0.8 V to 3.6 V, allowing translation between different voltage nodes such as 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V.
