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.
