4 / 18 page M27C4002 4/18 Standby Mode The M27C4002 has a standby mode which reduc- es the supply current from 50mA to 100µA. The M27C4002 is placed in the standby mode by ap- plyingaCMOS highsignal tothe E input. When in the 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, the 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, E should be decoded and used as the prima- 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. This ensures that all deselect- ed memory devices are in their low power standby mode and that the output pins are only active when data is required from a particular memory device. Table 5.
