This datasheet also covers the PY263 variant, as both devices belong to the same 8k x 8 reprogrammable prom family and are provided as variant models within a single manufacturer datasheet.
General 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.
