74LVX573
Low Voltage Octal Latch with 3-STATE Outputs
General Description
The LVX573 is a high-speed octal latch with buffered com-
mon Latch Enable (LE) and buffered common Output
Enable (OE) inputs. The LVX573 is functionally identical to
the LVX373 but with inputs and outputs on opposite sides
of the package. The inputs tolerate up to 7V allowing inter-
face of 5V systems to 3V systems.
Features
s Input voltage translation from 5V to 3V
s Ideal for low power/low noise 3.3V applications
s Guaranteed simultaneous switching noise level and
dynamic threshold performance

Functional Description
The LVX573 contains eight D-type latches. When the
enable (LE) input is HIGH, data on the Dn inputs enters the
latches. In this condition the latches are transparent, i.e., a
latch output will change state each time its D input
changes. When LE is LOW the latches store the informa-
tion that was present on the D inputs a setup time preced-
ing the HIGH-to-LOW transition of LE. The 3-STATE
buffers are controlled by the Output Enable (OE) input.
When OE is LOW, the buffers are enabled. When OE is
HIGH the buffers are in the high impedance mode but this
does not interfere with entering new data into the latches.

Note 1: The “Absolute Maximum Ratings” are those values beyond which
the safety of the device cannot be guaranteed. The device should not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the absolute maximum ratings.
The “Recommended Operating Conditions” table will define the conditions
for actual device operation.
Note 2: Unused inputs must be held HIGH or LOW. They may not float.
