Power-up reset
Power-up 3-State
No bus current loading when output is tied to 5V bus

DESCRIPTION
The 74ALVT16373 is a high-performance BiCMOS product
designed for V
CC
operation at 2.5V or 3.3V with I/O compatibility up
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.

NOTES:
1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability.
2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction
temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150
C.
3. The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.
