Standby Mode
The M27V160 hasa standby mode which reduces
the activecurrent from20mAto 20
μ
A with lowvolt-
age operation V
CC
3.6V, see Read Mode DC
Characteristics table for details.The M27V160 is
placed in the standby mode by applying a CMOS
high signal to the E input. When in the standby
mode, the outputs are in a high impedance 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.
