M54HC670 - 4 WORD x 4 BIT REGISTER FILE

General 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.
