DESCRIPTION
The 74LVT373 device is designed specifically
for low–voltage (3.3V) V
CC
operation, but can
provide a TTL interface to a 5V system
environment.
The 74LVT373 high-performance BiCMOS
device combines zero static and low dynamic
power dissipation with high speed and high
output drive.
The 74LVT373 device is an octal transparent
latch coupled to eight 3-State output buffers.
The two sections of the device are controlled
independently by Enable (E) and Output
Enable (OE) control gates.
The data on the D inputs are transferred to
the latch outputs when the Latch Enable (E)
input is High. The latch remains transparent
to the data inputs while E is High, and stores
the data that is present one setup time before
the High-to-Low enable transition.
The 3-State output buffers are designed to
drive heavily loaded 3-State buses, MOS
memories, or MOS microprocessors. The
active-Low Output Enable (OE) controls all
eight 3-State buffers independent of the latch
operation.
When OE is Low, the latched or transparent
data appears at the outputs. When OE is
High, the outputs are in the High-impedance
”O(jiān)FF” state, which means they will neither
drive nor load the bus.
