Notes on System Design

This IC adopts the ATD technique, in which operation starts when a change in either the CE or address inputs is detected.

This means that the output data immediately after power is applied is invalid. When using this IC as program memory for

the Z80 and similar microprocessors, applications must take into account the fact that valid data will not be output after

power is first applied unless the value of either the CE line or at least one of the address lines is changed after the power

supply has stabilized.

Another point due to the use of the ATD technique is that this IC is sensitive to input noise. Do not apply voltages

outside the allowable DC input levels for extended periods and do not apply input voltages with large noise components.
