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 (A0 to A12) will become available on the out-  
puts (O0 to 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).
