DESCRIPTION
The 74ABT373A high-performance BiCMOS device combines low
static and dynamic power dissipation with high speed and high
output drive.
The 74ABT373A 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
“OFF” state, which means they will neither drive nor load the bus.
