DESCRIPTION  
The M54/74HC670 is a high speed CMOS 4 WORD  
X 4 BIT REGISTER FILE (3-STATE) fabricated in  
silicon gate C2MOS technology. It has the same  
high speed performance of LSTTL combined with  
true CMOS low power consumption. The  
M54HC/74HC670 is a 4 x 4 Register File organized  
as four words by four bits. Separate read and write  
inputs, both address and enable, allow simulta-  
neous read and write operation. The 3-state outputs  
make it possible to connect up to 128 outputs to in-  
crease theword capacity up to 512 words. Anynum-  
ber of these devices can be operated in parallel to  
generate an n-bitlength. Allinputs areequipped with  
protection circuits against static discharge and tran-  
sient excess voltage.
