PY291A

2K X 8 REPROGRAMMABLE PROM

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 CS3 are HIGH. The memory contents

in the address established by the Address pins (A

0 to A10)

will become available on the outputs (O

0 to O7).

The PY291A is available in 24-pin 300 mil Ceramic DIPs

(CERDIP, Windowed and Non-Windowed) and Plastic

DIPs (Non-Windowed).
