Product specification
256-bit, 1-bit per word random access memories
HEF4720B
HEF4720V
Fig.9
Use of battery-operated LOCMOS gates to isolate the memory in case of power supply failure. Devices
marked (1) are connected to the battery. The HEF4011B can sink about 0,7 mA: if the load is greater than
this, only the memory should be connected, other loads being connected to the address latch as shown
by the dashed-line connections.
(1) These devices have a battery supply.
(2) Alternative connection.
