description/ordering information
The ’AHC573 devices are octal transparent
D-type latches designed for 2-V to 5.5-V VCC
operation.
When the latch-enable (LE) input is high, the
Q outputs follow the data (D) inputs. When LE is
low, the Q outputs are latched at the logic levels
of the D inputs.
A buffered output-enable (OE) input can be used
to place the eight outputs in either a normal logic
state (high or low) or the high-impedance state. In
the high-impedance state, the outputs neither
load nor drive the bus lines significantly. The
high-impedance state
and
increased
drive
provide the capability to drive bus lines without
interface or pullup components.
OE does not affect the internal operations of the
latches. Old data can be retained or new data can
be entered while the outputs are in the
high-impedance state.
To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
