SN74LV573AT
OCTAL TRANSPARENT D-TYPE LATCH
WITH 3-STATE OUTPUTS
SCES574C – JUNE 2004 – REVISED AUGUST 2005
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.
To ensure the high-impedance state during power up or power down, OE shall be tied to VCC through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
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.
This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs,
preventing damaging current backflow through the device when it is powered down.
