• ESD protection exceeds 2000 V per MIL STD 883 Method 3015
and 200 V per Machine Model
DESCRIPTION
The 74LVT162373 is a high-performance BiCMOS product designed
for V
CC
operation at 3.3 V.
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.
The 74LVT162373 is designed with 30 Ω series resistance in both
the High and Low states of the output. This design reduces the
noise in applications such as memory address drivers, clock drivers,
and bus receivers/transmitters.
