SN54ABT16821 - 20-BIT BUS-INTERFACE FLIP-FLOPS

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, bidirectional bus drivers with parity, and working registers.
