DESCRIPTION

The PY263 and PY264 are 8Kx8 CMOS PROMs. The

devices are 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

requires 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 (A₀to A₁₂) will become available on the out-

puts (O₀to O₇).

The PY263 is available in 24-pin 300 mil Ceramic DIPs

(Windowed) and Plastic DIPs (Non-Windowed).

The PY264 is available in 24-pin 600 mil Ceramic DIPs

(Windowed) and Plastic DIPs (Non-Windowed).
