FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION:
The LVCH162244A 16-bit buffer/driver is built using advanced dual
metal CMOS technology. The LVCH162244A is designed specifically to
improve both the performance and density of 3-state memory address
drivers, clock drivers, and bus-oriented receivers and transmitters. The
device can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer.
This device provides true outputs and symmetrical active-low output-enable
(OE) inputs.
All pins of this 16-bit buffer/driver can be driven from either 3.3V or 5V
devices. This feature allows the use of this device as a translator in a mixed
3.3V/5V supply system.
The LVCH162244A has series resistors in the device output structure
which will significantly reduce line noise when used with light loads. This
driver has been developed to drive ±12mA at the designated threshold
levels.
The LVCH162244A has âbus-holdâ which retains the inputsâ last state
whenever the input goes to a high impedance. This prevents floating inputs
and eliminates the need for pull-up/down resistors.
