| P4C150 ULTRA HIGH SPEED 1K X 4 RESETTABLE STATIC CMOS RAM FEATURES Full CMOS, 6T Cell High Speed (Equal Access and Cycle Times) - 10/12/15/20/25 ns (Commercial) - 15/20/25/35 ns (Military) Chip Clear Function Low Power Operation Single 5V 10% Power Supply Separate Input and Output Ports Three-State Outputs Fully TTL Compatible Inputs and Outputs Standard Pinout (JEDEC Approved) - 24-Pin 300 mil DIP - 24-Pin 300 mil SOIC - 28-Pin LCC (350 x 550 mils) - 24-Pin CERPACK DESCRIPTION The P4C150 is a 4,096-bit ultra high-speed static RAM organized as 1K x 4 for high speed cache applications. The RAM features a reset control to enable clearing all words to zero within two cycle times. The CMOS memory requires no clocks or refreshing, and has equal access and cycle times. Inputs and outputs are fully TTLcompatible. The RAM operates from a single 5V 10% tolerance power supply. Access times as fast as 10 nanoseconds are available permitting greatly enhanced system operating speeds. Time required to reset is only 20 ns for the 10 ns SRAM. CMOS is used to reduce power consumption to a low level. The P4C150 is available in 24-pin 300 mil DIP and SOIC packages providing excellent board level densities. The device is also available in a 28-pin LCC package as well as a 24-pin FLATPACK for military applications.

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.

Thevenin Equivalent 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 VCC and ground planes directly up to the contactor fingers. A 0.01 F high frequency capacitor is also required between VCC and ground. To avoid signal reflections, proper termination must be used; for example, a 50 test 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 series with DOUT to match 166 (Thevenin Resistance).
