8 REPROGRAMMABLE PROM
DESCRIPTION
The PY264 is an 8Kx8 CMOS PROM. The device is
available in windowed packages which when exposed to
UV light, the memory content in the PROM is erased and
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.
To perform a read operation from the device,
CS
is LOW.
The memory contents in the address established by the
Address pins (A
0
to A
12
) will become available on the
outputs (O
0
to O
7
).
The PY264 is available in 24-pin 600 mil Ceramic DIPs
(Windowed) and Plastic DIPs (Non-Windowed).
