The device is fully specified for partial power down applications using IOFF. The IOFF circuitry disables the 1OE Vcc 19 Vcc 20 2 1 1 20 1OE The device is designed for operation with a power supply range of 1.65V to 3.6V.   ( Top Transparent View) terminal 1 index area 2A1 The 74LVC240A provides two 4-bit buffers/drivers with separate output-enable (OE) inputs. When OE is low, the device passes data from the A inputs to the Y outputs. When OE is high, the outputs are in the high-impedance state.
