74AVCH4T245PW,118

74AVCH4T245PW,118 is a 4bit, dual supply transceiver that enables bidirectional level translation. This device can be used as two 2bit transceivers or as a 4bit transceiver. It features two 2bit input-output ports (nAn and nBn), a direction control input, an output enable input, and dual supply pins (VCC(A) and VCC(B)). Both VCC(A) and VCC(B) can be supplied at any voltage between 0.8V and 3.6V making the device suitable for translating between any of the low-voltage nodes (0.8V, 1.2V, 1.5V, 1.8V, 2.5V and 3.3V). Pins nAn, n active-low OE, and nDIR are referenced to VCC(A) and pins nBn are referenced to VCC(B). A HIGH on nDIR allows transmission from nAn to nBn and a LOW on nDIR allows transmission from nBn to nAn. The output enables input can be used to disable the outputs so the buses are effectively isolated. The device is fully specified for partial-power-down applications using IOFF.
