U74LVC563
OCTAL TRANSPARENT D-TYPE
LATCHES WITH 3-STATE OUTPUTS
DESCRIPTION
The U74LVC563 is a octal transparent D-TYPE latches with 3-state
outputs. When the latch-enable (LE) is high, the Q outputs follow the
complements of the D inputs. When LE is low, the Q outputs are latched at
the inverses of the levels set up at the D inputs.
When the output-enable ( OE ) input is high, the Q outputs are in a
high-impedance state, and the outputs neither load nor drive the bus lines.
The high-impedance state and increased drive provide the capability to drive
bus lines without interface or pull-up components. While the outputs are in
the high-impedance state, old data can be retained or new data can be
entered, i.e. OE does not affect the internal operations of the latches. When
OE is low, the Q outputs are in a normal logic state (high or low levels).
The U74LVC563 is designed for 1.65V to 3.6V operation. Inputs can be
driven from either 3.3V or 5V devices, so the U74LVC563 can be used in a
mixed 3.3V/5V system environment.
To ensure the high-impedance state during power up or power down,
OE should be tied to VCC through a pull-up resistor; the minimum value of
the resistor is determined by the current-sinking capability of the driver.
