2 Description
The ’AC564 devices are octal D-type edge-triggered flip-flops that feature inverting 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.
