Note:
1. Minimum DC voltage on input or I/O pins 0.5 V. During voltage transitions, the input may overshoot V_SS to 2.0 V for periods of up to 20 ns. Maximum DC voltage on input and I/O pins is V_CC + 5 V. During voltage transitions, input and I/O pins may overshoot to V_CC + 2.0 V for periods up to 20ns.

Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure of the device to absolute maximum ratings for extended periods may affect device reliability.

The Am27X64 is a factory programmed and tested OTP EPROM. It is programmed after packaging prior to final test. Every device is rigorously tested under AC and DC operating conditions to your stable code. It is organized as 8 Kwords by 8 bits per word and is available in plastic dual in-line packages (PDIP), as well as plastic leaded chip carrier (PLCC) packages. Express- ROM devices Am27X64 provide a board-ready memory solution for medium to high volume codes with short leadtimes. This offers manufacturers a cost-effective and flexible alternative to OTP EPROMs and mask programmed ROMs.

Data can be accessed as fast as 55 ns, allowing high-performance microprocessors to operate with reduced WAIT states. Am27X64 offers separate Output Enable (OE#) and Chip Enable (CE#) controls, thus eliminating bus contention in a multiple bus microprocessor system.

AMD's CMOS process technology provides high speed, low power, and high noise immunity. Typical power consumption is only 80 mW in active mode, and 100 W in standby mode.
