3.3-V ABT OCTAL TRANSPARENT D-TYPE LATCHES WITH 3-STATE OUTPUTSThese octal Latches are designed specifically for low-voltage (3.3-V) VCC operation, but with the capability to
provide a TTL Interface to a 5-V system environment.
The eight Latches of the LVT573 are transparent D-type Latches While the latch-enable (LE) input is high, the
Q outputs follow the data (D) inputs. When LE is taken low, the Q outputs are latched at the Logic levels set up
at 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 Logic levels) or a 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 need for 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.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid Logic level.
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.
The SN74LVT573 is available in TIs shrink small-outline package (DB), which provides the same I/O pin count
and functionality of standard small-outline packages in less than half the printed-circuit-board area.
The SN54LVT573 is characterized for operation over the full military temperature range of 55C to 125C. The
SN74LVT573 is characterized for operation from 40C to 85C. By Texas Instruments
