DESCRIPTIOꢀ
The P4C1256 is a 262,144-bit high-speed CMOS static
RAM organized as 32K x 8. The CMOS memory requires
no clocks or refreshing, and has equal access and cycle
times. InputsarefullyTTL-compatible. TheRAMoperates
from a single 5V±10% tolerance power supply.
with matching access and cycle times. Memory locations
are specified on address pinsA0 toA14. Reading is accom-
plished by device selection (CE) and output enabling (OE)
while write enable (WE) remains HIGH. By presenting the
address under these conditions, the data in the addressed
memorylocationispresentedonthedatainput/outputpins.
The input/output pins stay in the HIGH Z state when either
CE or OE is HIGH or WE is LOW.
Access times as fast as 12 nanoseconds permit greatly
enhanced system operating speeds. CMOS is utilized to
reduce power consumption to a low level. The P4C1256
is a member of a family of PACE RAM™ products offering
fast access times.

1. Stresses greater than those listed under MAꢀIMUM 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 MAꢀIMUM rating conditions for extended
periods may affect reliability.
4. This parameter is sampled and not 100% tested.
5. WE is HIGH for READ cycle.
6. CE is LOW and OE is LOW for READ cycle.
7. ADDRESS must be valid prior to, or coincident with CE transition
LOW.
8. Transition is measured ± 200 mV from steady state voltage prior to
change,withloadingasspecifiedinFigure1. Thisparameterissampled
and not 100% tested.
2. Extended temperature operation guaranteed with 400 linear feet per
minute of air flow.
9. Read Cycle Time is measured from the last valid address to the first
transitioning address.
3. Transient inputs with VIL and IIL not more negative than –3.0V and
–100mA, respectively, are permissible for pulse widths up to 20ns.

ꢀote:
Becauseoftheultra-highspeedoftheP4C1256,caremustbetakenwhen
testing this device; an inadequate setup can cause a normal function-
ing 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. To avoid signal reflections,
proper termination must be used; for example, a 50Ω test environment
should be terminated into a 50Ω load with 1.73V (Thevenin Voltage) at
the comparator input, and a 116Ω resistor must be used in series with
DOUT to match 166Ω (Thevenin Resistance).
