P4C163 PYRAMID [Pyramid Semiconductor Corporation], P4C163 Datasheet - Page 7

• Manufacturer Part Number: P4C163
• Description: ULTRA HIGH SPEED 8K x 9 STATIC CMOS RAMS
• Manufacturer: PYRAMID [Pyramid Semiconductor Corporation]

* including scope and test fixture.
Note:
Because of the ultra-high speed of the P4C163/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 V
planes directly up to the contactor fingers. A 0.01 µF high frequency

reflections, proper termination must be used; for example, a 50
environment should be terminated into a 50 load with 1.73V (Thevenin
Voltage) at the comparator input, and a 116 resistor must be used in
