DESCRIPTION
The P4C107 is a 1Mx1-bit ultra high-speed static RAM.
The CMOS memories require no clocks or refreshing and
have equal access and cycle times. The RAM operates
from a single 5V ± 10% tolerance power supply. Data
integrity is maintained for supply voltages down to 2.0V,
typically drawing 50µA.
Functional Block Diagram
Access times as fast as 10 nanoseconds are available,
greatly enhancing system speeds.
The P4C107 is available in a 28-pin 400 mil SOJ.

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 20 ns.

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, with loading as specified in Figure 1. This parameter is sampled
and not 100% tested.
9.Read Cycle Time is measured from the last valid address to the first
transitioning address.

Note:
Because of the ultra-high speed of the P4C107, 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
Notes:
10. CE and WE must be LOW for WRITE cycle.
11. OE is LOW for this WRITE cycle to show tWZ and tOW.
12. If CE goes HIGH simultaneously with WE HIGH, the output remains
in a high impedance state

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).
13. Write Cycle Time is measured from the last valid address to the first
transitioning address.
