Overview
The 74AVCH4T245PW-Q10J, produced by Nexperia USA Inc., is a 4-bit dual supply translating transceiver designed for bidirectional level translation. This device can be used as two 2-bit transceivers or as a single 4-bit transceiver, making it versatile for various applications. It features two 2-bit input-output ports (nAn and nBn), a direction control input (nDIR), and an output enable input (nOE), along with dual supply pins (VCC(A) and VCC(B)) that can operate within a wide voltage range of 0.8 V to 3.6 V. This component is particularly useful for translating 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.
