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 simultaneous read and write operation. The 3-state outputs
make it possible to connect up to 128 outputs to increase the word capacity up to 512 words. Any number of these devices can be operated in parallel to
generate an n-bit length. All inputs are equipped with
protection circuits against static discharge and transient excess voltage.

(*) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without load.
(Refer to Test Circuit). Average operting current can be obtained by the following equation. ICC(opr) = CPD •VCC •fIN + ICC
