Data flow is controlled by output-enable (OE), latch-enable (LE), and clock (CLK) inputs. The device operates in Transparent Mode when LE is held HIGH. The device operates in clocked mode when LE is LOW and CLK is toggled. Data transfers from the Inputs (In) to Ouputs (O n) on a Positive Edge Transition of the Clock. When OE is LOW, the output data is enabled. When OE is HIGH the output port is in a high impedance state. The 74VCX16835 is designed for low voltage (1.65V to 3.6V) VCC applications with I/O capability up to 3.6V. The 74VCX16835 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining low CMOS power dissipation.
