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  
andcanbereprogrammed.EPROMtechnologyisusedin  
thememorycellsforprogramming.TheEPROMrequires  
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.  
and CS2 and CS3 are HIGH. The memory contents in the  
address established by the Address pins (A0 to A10) will  
become available on the outputs (O0 to O7).  
The PY291Ais available in 24-pin 300 mil Ceramic DIPs  
(CERDIP, Windowed and Non-Windowed) and Plastic  
DIPs (Non-Windowed).  
To perform a read operation from the device, CS1 is LOW
