Standby Mode

The M27V800 has a standby mode which reduces

the supply current from 20mA to 20

µA with low

voltage operation VCC ≤ 3.6V, see Read Mode DC

Characteristics table for details.The M27V800 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.
