DESCRIPTION
The 74ABT573A high-performance BiCMOS device combines low
static and dynamic power dissipation with high speed and high
output drive.
The 74ABT573A 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 74ABT573A is functionally identical to the
74ABT373 but has a flow-through 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.
