description/ordering information
These 8-bit flip-flops feature 3-state outputs 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 eight flip-flops of the SN54ABT574 and SN74ABT574A are edge-triggered D-type flip-flops. On the positive
transition of the clock (CLK) input, the Q outputs are set to the logic levels set up at the data (D) inputs.
