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 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 (A0 to A12) will become available on the outputs (O0 to O7).
The PY264 is available in 24-pin 600 mil Ceramic DIPs (Windowed) and Plastic DIPs (Non-Windowed).
