74ALVC16835 Low Voltage 18-Bit Universal Bus Driver with 3.6V Tolerant Inputs and Outputs September 2001 Revised February 2002 74ALVC16835 Low Voltage 18-Bit Universal Bus Driver with 3.6V Tolerant Inputs and Outputs General Description The ALVC16835 low voltage 18-bit universal bus driver combines D-type latches and D-type flip-flops to allow data flow in transparent, latched and clocked modes. 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 74ALVC16835 is designed for low voltage (1.65V to 3.6V) VCC applications with I/O capability up to 3.6V. The 74ALVC16835 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining low CMOS power dissipation.
