DESCRIPTION
The LVT573 is a high-performance BiCMOS product designed for
V
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 74LVT573 has a broadside pinout
configuration to facilitate PC board layout and allow easy interface
with microprocessors.
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
“OFF” state, which means they will neither drive nor load the bus.
