Two Line Output Control
Because EPROMs are usually used in larger
memory arrays, this product features a 2 line con-
trol function which accommodates the use of mul-
tiple memory connection. The two line control
function allows:
a. the lowest possible memory power dissipation
b. complete assurance that output bus contention
will not occur.
For the most efficient use of these two control
lines, Eshould be decodedand used as theprima-
ry device selecting function, while G should be
made a common connection to all devices in the
array and connected to the READ line from the
system controlbus. This ensures that all deselect-
ed memory devices are in their lowpower standby
mode and that the output pins are only active
when data is required from a particular memory
device.
System Considerations
The power switching characteristics of Advanced
CMOS EPROMs require careful decoupling of the
devices. The supply current, I
CC
, has three seg-
ments that are of interest to the system designer:
the standby current level, the active current level,
and transient current peaks that are produced by
the fallingand rising edges of E. The magnitude of
the transient current peaks is dependent on the
capacitive and inductive loading of the device at
the output.
