SN74ABT16823 具有三态输出的 18 位总线接口触发器

These 18-bit bus-interface flip-flops feature 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. They are particularly suitable for implementing wider buffer registers, I/O ports, bidirectional bus drivers with parity, and working registers.

The ’ABT16823 devices can be used as two 9-bit flip-flops or one 18-bit flip-flop. With the clock-enable (CLKEN)\ input low, the D-type flip-flops enter data on the low-to-high transitions of the clock. Taking CLKEN\ high disables the clock buffer, thus latching the outputs. Taking the clear (CLR)\ input low causes the Q outputs to go low independently of the clock.

A buffered output-enable (OE)\ input places the nine outputs in either a normal logic state (high or low level) or a high-impedance state
