DESCRIPTION
Toperformareadoperationfromthedevice,CSisLOW.
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 an 8Kx8 CMOS PROM. The device is
availableinwindowedpackageswhichwhenexposedto
UVlight,thememorycontentinthePROMiserasedand
can be reprogrammed. EPROM technology is used in
the memory cells for programming. The EPROM re-
quires 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.
The PY264 is available in 24-pin 600 mil Ceramic DIPs
(Windowed) and Plastic DIPs (Non-Windowed).

TIMING WAVEFORM OF READ CYCLE
Notes:
1. Stresses greater than those listed under MAXIMUM RATINGS may
cause permanent damage to the device. This is a stress rating only
and functional operation of the device at these or any other conditions
above those indicated in the operational sections of this specification
is not implied. Exposure to MAXIMUM rating conditions for extended
periods may affect reliability.
2. Extended temperature operation guaranteed with 400 linear feet per
minute of air flow.
3. Transient inputs with VIL and IIL not more negative than –3.0V and
–100mA, respectively, are permissible for pulse widths up to 20ns.
4. This parameter is sampled and not 100% tested.

DEVICE ERASURE
25 Wsec/cm2. If using a UV lamp of 12 mW/cm2, the
exposure time is estimated to be 35 minutes. Devices
should be positioned within 1 inch of the lamp during the
erasure process. Permanent damage can occur to the
devices if exposed to UV light for an extended period of
time.
If the device is subjected to wavelengths of light below
4000 Angstroms, device erasure will commence. It is
thereforerecommendedtouseanopaquelabeloverthe
windowintheeventthedevicewillbeexposedtolighting
for a long time. The UV dose for erasure requires a
wavelength of 2,537 Angstroms for a minimum dose of
READ MODE
Reading the addressed content is the normal operating
mode for a programmed device. Signals are at normal
TTLlevels. Addressingisappliedtothe13addresspins
and CS is LOW. Under these conditions, the addressed
location contents are presented to the output pins.

Note:
Because of the ultra-high speed of the PY264, care must be taken when
testing this device; an inadequate setup can cause a normal functioning
part to be rejected as faulty. Long high-inductance leads that cause
supply bounce must be avoided by bringing the VCC and ground planes
directly up to the contactor fingers. A 0.01 µF high frequency capacitor
is also required between VCC and ground.
