Product specification
HEF4720B
HEF4720V
DESCRIPTION
The HEF4720B and HEF4720V are 256-bit, 1-bit per word
random access memories with 3-state outputs. The
memories are fully decoded and completely static.
Recommended supply voltage range for HEF4720B is 3 to
15 V and for HEF4720V is 4,5 to 12,5 V; minimum
stand-by voltage for both types is 3 V.
The use of LOCMOS gives the added advantage of very
low stand-by power. The circuits can be directly interfaced
with standard bipolar devices (TTL) without using special
interface circuits. The memory operates from a single
power supply. The separate chip select input (CS) allows
simple memory expansion when the outputs are wire-O
Red. If CS is HIGH, the outputs are floating and no new
information can be written into the memory. The signal at
O has the same polarity as the data input D, while the
signal at O is the complement of the signal at O. The write
control W must be HIGH for writing into the memory.
