DESCRIPTION
The P4C167/L are 16,384-bit high speed static RAMs organized as 16K x 1. The CMOS memories require no clocks
or refreshing and have equal access and cycle times. The
RAMs operate from a single 5V ± 10% tolerance power
supply. Data integrity is maintained for supply voltages
down to 2.0V, typically drawing 10µA.
Access times as fast as 10 nanoseconds are available,
greatly enhancing system speeds. CMOS reduces power
consumption to low levels.

PIN CONFIGURATIONS
The P4C167/L are available in 20-pin 300 mil DIP, 20-pin
300 mil SOJ, and 20-pin LCC packages providing excellent board level densities.

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.
Document # SRAM106 REV A
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.

Notes:
5. CE is LOW and WE is HIGH for READ cycle.
6. WE is HIGH, and address must be valid prior to or coincident with CE
transition LOW.

7. Transition is measured ±200mV from steady state voltage prior to
change with specified loading in Figure 1. This parameter is sampled
and not 100% tested.
8. Read Cycle Time is measured from the last valid address to the first
transitioning address.

Note:
Due to the ultra-high speed of the P4C167/L, 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. To avoid signal reflections,
Document # SRAM106 REV A
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).
