DESCRIPTION:
This 16-bit transparent D-type latch is built using advanced CMOS technol-
ogy. The device can be used as a single 16-bit latch or as two 8-bit latches. When
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 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 OE input does not affect the internal operation of the latch.
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.
To ensure the high-impedance state during power up or power down, OE
should be tied to VDD through a pull-up resistor; the minimum value of the resistor
is determined by the current-sinking capability of the driver.
