CJ74LVC8T245BHN

The CJ74LVC/LVCH8T245 is an 8-bit dual-supply level-translating transceiver with 3-state outputs, supporting bidirectional voltage translation. The device features two data I/O ports (pins An and Bn), a direction control input (DIR), an output enable input (/OE), and dual supply pins VCC(A) and VCC(B). Both VCC(A) and VCC(B) can be powered at any voltage between 1.2V and 5.5V, making the device suitable for level translation between any low-voltage nodes (1.2V, 1.5V, 1.8V, 2.5V, 3.3V, and 5.0V). Pins An, /OE, and DIR are referenced to VCC(A), while pin Bn is referenced to VCC(B). When DIR is HIGH, data transmission is enabled from An to Bn; when DIR is LOW, data transmission is enabled from Bn to An. The output enable input (/OE) can be used to disable the outputs, effectively isolating the bus. The device fully supports partial power-down applications via the IOFF feature. The IOFF circuitry disables the outputs to prevent any damaging backflow current when the device is powered down. In power-off mode, when VCC(A) or VCC(B) is at GND level, both port A and port B are in a high-impedance off state. The active bus-hold circuitry in the CJ74LVCH8T245 holds unused or floating data inputs at a valid logic level.
