These octal D-type edge-triggered flip-flops  
feature 3-state outputs designed specifically for  
bus driving. They are particularly suitable for  
implementing buffer registers, I/O ports,  
bidirectional bus drivers, and working registers.  
SN54ALS576B, SN54AS576 . . . FK PACKAGE  
(TOP VIEW)  
These flip-flops enter data on the low-to-high  
transition of the clock (CLK) input.
