74LVCH245APW,118

74LVCH245APW,118 is an 8bit bus transceiver with 3-state outputs. This device features an output enable and send/receive (DIR) for direction control. A HIGH on active-low OE causes the outputs to assume a high-impedance OFF-state. Inputs can be driven from either 3.3V or 5V devices. This feature allows the use of this device as a translator in mixed 3.3V and 5V environments. Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times. This device is fully specified for partial-power-down applications using IOFF. The IOFF circuitry disables the output, preventing the potentially damaging backflow current through the device when it is powered down. It complies with JEDEC standard (JESD8-7A (1.65V to 1.95V), JESD8-5A (2.3V to 2.7V), JESD8-C/JESD36 (2.7V to 3.6V). It features ESD protection (HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000V, CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000V).
