P4C150-10CC PYRAMID [Pyramid Semiconductor Corporation], P4C150-10CC Datasheet - Page 6

• Manufacturer Part Number: P4C150-10CC
• Description: ULTRA HIGH SPEED 1K X 4 RESETTABLE STATIC CMOS RAM
• Manufacturer: PYRAMID [Pyramid Semiconductor Corporation]

AC TEST CONDITIONS
* including scope and test fixture.
Note:
Due to the ultra-high speed of the P4C150, 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 V
contactor fingers. A 0.01 µF high frequency capacitor is also required

into a 50 load with 1.73V (Thevenin Voltage) at the comparator input, and
a 116 resistor must be used in series with D
