74ALVCF162835
Low Voltage 18-Bit Universal Bus Driver with 3.6V
Tolerant Outputs and 26 Ω Series Resistors in Outputs
General Description
The 74ALVCF162835 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 (I
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 74ALVCF162835 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
transceivers/transmitters.
The 74ALVCF162835 is designed for low voltage (1.65V to
3.6V) V
The 74ALVCF162835 is fabricated with an advanced
CMOS technology to achieve high speed operation while
maintaining low CMOS power dissipation.
