• Manufacturer Part Number: p4c164-12cwmlf
• Description: Ultra High Speed Static Cmos Rams
• Manufacturer: Pyramid Semiconductor Corporation

* including scope and test fixture.
Note:
Because of the high speed of the P4C164/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
directly up to the contactor fingers. A 0.01 µF high frequency capacitor
is also required between V
