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.

The output-enable (OE) input does not affect  
internal operations of the flip-flops. Old data can  
be retained or new data can be entered while the

The SN54ALS576B and SN54AS576 are  
characterized for operation over the full military  
temperature range of 55°C to 125°C. The  
SN74ALS576B,  
SN74AS576 are characterized for operation from  
0°C to 70°C.
