DESCRIPTION
The 74LVT16373A is a high-performance BiCMOS product
designed for VCC operation at 3.3V.
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 enable (E) input is High, the
Q outputs follow the data (D) inputs. When 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.

transition time of 100µsec is permitted. This parameter is valid for Tamb = 25°C only.
4. Unused pins at VCC or GND.
5. For valid test results, data must not be loaded into the flip-flops (or latches) after applying power.
6. ICCZ is measured with outputs pulled to VCC or GND.
7. This is the bus hold overdrive current required to force the input to the opposite logic state.
