FEATURES
DESCRIPTION
The 74ABT16373B high-performance BiCMOS device combines
low static and dynamic power dissipation with high speed and high
output drive.
The 74ABT16373B 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.
Two options are available, 74ABT16373B which does not have the
bus-hold feature and 74ABTH16373B which incorporates the
bus-hold feature.
