DESCRIPTION
The PY291A is a 2Kx8 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
1
is
LOW and CS
2
and CS
3
are HIGH. The memory contents
in the address established by the Address pins (A
0
to A
10
)
will become available on the outputs (O
0
to O
7
).
The PY291A is available in 24-pin 300 mil Ceramic DIPs
(CERDIP, Windowed and Non-Windowed) and Plastic
DIPs (Non-Windowed).
