(TOP VIEW)  
These dual 4-bit D-type edge-triggered flip-flops  
feature 3-state outputs designed specifically as  
bus drivers. They are particularly suitable for  
implementing buffer registers, I/O ports,  
bidirectional bus drivers, and working registers.

The edge-triggered flip-flops enter data on the  
low-to-high transition of the clock (CLK) input.  
The SN54ALS874B, SN74ALS874B, and  
SN74AS874 have clear (CLR) inputs and  
noninverting Q outputs. The SN74ALS876A and  
SN74AS876 have preset (PRE) inputs and  
inverting Q outputs; taking PRE low causes the  
four Q or Q outputs to go low independently of the  
clock.

The SN54ALS874B is characterized for operation  
NC − No internal connection  
over the full military temperature range of 55°C  
to 125°C. The SN74ALS874B, SN74ALS876A,  
SN74AS874, and SN74AS876 devices are  
characterized for operation from 0°C to 70°C.
