DESCRIPTION
The MB2373 high-performance BiCMOS
device combines low static and dynamic
power dissipation with high speed and high
output drive.
The MB2373 device is a dual octal
transparent latch coupled to two sets of eight
3-State output buffers. The two sections of
the device are controlled independently by
Enable (nE) and Output Enable (nOE) control
gates.
The data on each set of D inputs are
transferred to the latch outputs when the
Latch Enable (nE) input is High. The latch
remains transparent to the data inputs while
nE 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. Each
active-Low Output Enable (nOE) controls
eight 3-State buffers independent of the latch
operation.
When nOE is Low, the latched or transparent
data appears at the outputs. When nOE is
High, the outputs are in the High–impedance
“OFF” state, which means they will neither
drive nor load the bus.
