Overview
The 74AVC4T245GU-Q100X, produced by Nexperia USA Inc., is a 4-bit, dual supply transceiver designed to enable bidirectional level translation. This device can be utilized as two 2-bit transceivers or as a single 4-bit transceiver, making it highly versatile in various electronic designs. It features four 2-bit input-output ports (nAn and nBn), a direction control input (nDIR), an output enable input (nOE), and dual supply pins (VCC(A) and VCC(B)) that can operate at any voltage between 0.8 V and 3.6 V. This flexibility allows the device to translate between different low voltage nodes such as 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V.
