description/ordering information
The
’ACT563
devices
are
octal
D-type
transparent latches with 3-state outputs. When
the latch-enable (LE) input is high, the Q outputs
are set to the complements of the data (D) inputs.
When LE is taken low, the Q outputs are latched
at the inverse logic levels set up at the D inputs.
A buffered output-enable (OE) input places the
eight outputs in either a normal logic state (high or
low logic levels) 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 high logic
level provide the capability to drive bus lines
without interface or pullup components.
OE does not affect 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.
