Input and output interface capability to systems at 5V supply
Bus-hold data inputs eliminate the need for external pull-up
resistors to hold unused inputs
Live insertion/extraction permitted
Power-up reset
Power-up 3-State
No bus current loading when output is tied to 5V bus
Latch-up protection exceeds 500mA per JEDEC Std 17
ESD protection exceeds 2000V per MIL STD 883 Method 3015
and 200V per Machine Model
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.
