3 Description
The SNx4AHC574 devices are octal edge-triggered
D-type flip-flops that feature 3-state outputs designed
specifically for driving highly capacitive or relatively
low-impedance loads. These devices are particularly
suitable for implementing buffer registers, I/O ports,
bidirectional bus drivers, and working registers.
