74VCXF162835
Low Voltage 18-Bit Universal Bus Driver with 3.6V
Tolerant Outputs and 26Series Resistors in Outputs
General Description
Features
The VCXF162835 low voltage 18-bit universal bus driver s Compatible with PC133 DIMM module specifications
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
s 1.65V–3.6V VCC specifications provided
s 3.6V tolerant outputs
s 26series resistors in outputs
s tPD (CLK to On)
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 26series resistors in
the outputs. This design reduces noise in applications such
as memory address drivers, clock drivers, and bus trans-
