| P4C167/P4C167L ULTRA HIGH SPEED 16K X 1 STATIC CMOS RAMS FEATURES Full CMOS, 6T Cell High Speed (Equal Access and Cycle Times) - 10/12/15/20/25 ns (Commercial) - 12/15/20/25/35 ns (Industrial) - 15/20/25/35/45 ns (Military) Low Power Operation Single 5V10% Power Supply Data Retention with 2.0V Supply (P4C167L Military) Separate Data I/O Three-State Output TTL Compatible Output Fully TTL Compatible Inputs Standard Pinout (JEDEC Approved) - 20-Pin 300 mil DIP - 20-Pin 300 mil SOJ - 20-Pin LCC 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 10A. Access times as fast as 10 nanoseconds are available, greatly enhancing system speeds. CMOS reduces power consumption to low levels. 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.

Output Load * including scope and test fixture. 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 F high frequency capacitor is also required between VCC and ground. To avoid signal reflections, Figure 2. Thevenin Equivalent 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).
