Standby Mode
The M27C160 has a standby mode which reduces
the active current from 50mA to 100
μ
A. The
M27C160 is placed in the standby mode by apply-
ing aCMOS high signal to the Einput. When inthe
standby mode, the outputs are in a high imped-
ance state, independent of the G input.
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 decoded and 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 control bus. Thisensures 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.
