description  
The ’ABT16843 18-bit bus-interface D-type  
latches are designed specifically for driving highly  
capacitive or relatively low-impedance loads.  
They are particularly suitable for implementing  
buffer registers, I/O ports, bidirectional bus  
drivers, and working registers.

The ’ABT16843 can be used as two 9-bit latches  
or one 18-bit latch. The 18 latches are transparent  
D-type latches. The device provides true data at  
its outputs.  
A buffered output-enable (OE) input can be used  
to place the nine outputs in either a normal logic  
state (high or low logic levels) or  
a
high-impedance state. The outputs are in the  
high-impedance state during power up and power  
down. The outputs remain in the high-impedance  
state while the device is powered down. In the  
high-impedance state, the outputs neither load  
nor drive the bus lines significantly. The  
high-impedance state and increased drive  
provide the capability to drive bus lines without  
need for interface or pullup components.
