Ground
The DS1609 is a random access 256–byte dual port
memory designed to connect two asyncronous ad-
dress/data buses together with a common memory ele-
ment. Both ports have unrestricted access to all
by three control signals: output enable, write enable,
and port enable. The device is packaged in plastic
24–pin DIP and 24–pin SOIC. Output enable access
time of 50 ns is available when operating at 5 volts.
256 bytes of memory, and with modest system disci-
pline no arbitration is required. Each port is controlled
