54ACT16821 - 20-Bit Bus-Interface Flip-Flop

Description

These 20-bit 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, parity bus interfacing, and working registers.
