DESCRIPTION

The M54/74HC279 is a high speed CMOS QUAD S

- R LATCH fabricated in silicon gate C

MOS tech-

nology. It has the same high speed performance of

LSTTL combined with true CMOS low power con-

sumption.

All inputs are equipped with protection circuits

against static discharge and transient excess volt-

age.
