16-BIT TRANSPARENT D-TYPE LATCH

WITH 3-STATE OUTPUTS

SCAS755 – DECEMBER 2003 – REVISED MARCH 2005

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 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 internal operations of the latch. Old data can be retained or new data can be entered while

the outputs are in the high-impedance state.

Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of this device as a translator in

a mixed 3.3-V/5-V system environment.

resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

preventing damaging current backflow through the device when it is powered down.
