... ELECTRONIC SIGNATURE – Manufacturer Code: 9Bh – Device Code: 08h DESCRIPTION The M27C64A is a 64Kbit EPROM offered in the two ranges UV (ultra violet erase) and OTP (one time programmable ideally suited for micro- processor systems requiring large programs and is organized as 8,192 by 8 bits. ...

... Output is V +0.5V with possible overshoot Depends on range. DEVICE OPERATION The modes of operation of the M27C64A are listed in the Operating Modes table. A single power sup- ply is required in the read mode. All inputs are TTL levels except for V and 12V on A9 for Electronic PP Signature ...

... Standby Mode The M27C64A has a standby mode which reduces the active current from 30mA to 100 A. The M27C64A is placed in the standby mode by apply- ing 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. ...

... Except for E, all like inputs including G of the parallel M27C64A may be common. A TTL low level pulse applied to a M27C64A P input, with E low and V at 12.5V, will program that M27C64A. A high level 4/12 E input inhibits the other M27C64A from being programmed ...
