... 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- plying a CMOS high signal to the E input. When in the standby mode, the outputs are in a high imped- ance state, independent of the G input. ...

... CC 2. Sampled only, not 100% tested. Programming When delivered (and after each erasure for UV EPROM), all bits of the M27C4002 are in the '1' state. Data is introduced by selectively program- ming '0's into the desired bit locations. Although only '0's will be programmed, both '1's and '0's can be present in the data word. The only way to ...

... Ex- cept for E, all like inputs including G of the parallel M27C4002 may be common. A TTL low level pulse applied to a M27C4002's E input, with V at 12.75V, will program that M27C4002. A high level E input inhibits the other M27C4002s from being programmed ...
