1 / 8 page © 2000 Fairchild Semiconductor Corporation DS500259 www.fairchildsemi.com October 1999 Revised April 2000 74VCXF162835 Low Voltage 18-Bit Universal Bus Driver with 3.6V Tolerant Outputs and 26 Ω Series Resistors in Outputs General Description The VCXF162835 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 tog- gled. Data transfers from the Inputs (In) to Outputs (On) 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 VCXF162835 is designed with 26 Ω series resistors in the outputs. This design reduces noise in applications such as memory address drivers, clock drivers, and bus trans- ceivers/transmitters. The 74VCXF162835 is designed for low voltage (1.65V to 3.6V) VCC applications with I/O capability up to 3.6V. The 74VCXF162835 is fabricated with an advanced CMOS technology to achieve high speed operation while maintain- ing low CMOS power dissipation.
