DESCRIPTION
The M74HC670 is an high speed CMOS 4-
WORD x 4 BIT REGISTER FILE (3 STATE)
fabricated with silicon gate C2MOS technology.
The M74HC670 is 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.
