DESCRIPTION
The 74ALVT16373 is a high-performance BiCMOS product
designed for V
to 5V .
This device is a 16-bit transparent D-type latch with non-inverting
3-State bus compatible outputs. The device can be used as two
8-bit latches or one 16-bit latch. When latch enable (LE) input is
High, the Q outputs follow the data (D) inputs. When latch enable is
taken Low, the Q outputs are latched at the levels of the D inputs
one setup time prior to the High-to-Low transition.
