Description

General part information

SN74ABT16843 Series

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.
