DESCRIPTION

To perform a read operation from the device, CS₁is

LOW and CS₂and CS₃are HIGH. The memory contents

intheaddressestablishedbytheAddresspins(A₀toA₁₀)

will become available on the outputs (O₀to O₇).

The PY291A is a 2Kx8 CMOS PROM. The device is

availableinwindowedpackageswhichwhenexposedto

UVlight,thememorycontentinthePROMiserasedand

can be reprogrammed. EPROM technology is used in

the memory cells for programming. The EPROM re-

quires a 12.5V for programming. Devices are tested to

insure that performance of the device meets the DC and

AC specification limits after customer programming.
