| P4C188/P4C188L ULTRA HIGH SPEED 16K x 4 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 (Industrial) - 15/20/25/35/45 ns (Military) Low Power (Commercial/Military) - 715 mW Active - 12/15 - 550/660 mW Active - 20/25/35/45 - 193/220 mW Standby (TTL Input) - 83/110 mW Standby (CMOS Input) P4C188 - 15 mW Standby (CMOS Input) (P4C188L Military) Single 5V10% Power Supply Data Retention with 2.0V Supply (P4C188L Military) Three-State Outputs TTL/CMOS Compatible Outputs Fully TTL Compatible Inputs Standard Pinout (JEDEC Approved) - 22-Pin 300 mil DIP - 24-Pin 300 mil SOJ - 22-Pin 290 x 490 mil LCC DESCRIPTION The P4C188 and P4C188L are 65,536-bit ultra high speed static RAMs organized as 16K x 4. The CMOS memories require no clocks or refreshing and have equal access and cycle times. Inputs and outputs are fully TTL-compatible. The RAMs operate from a single 5V10% tolerance power supply. With battery backup, data integrity is maintained for supply voltages down to 2.0V. Current drain is typically 10 A from a 2.0V supply. Access times as fast as 10 nanoseconds are available, permitting greatly enhanced system speeds. CMOS is utilized to reduce power consumption to a low 715mW active, 193mW standby and only 5mW in the P4C188L version. The P4C188 and P4C188L are available in 22-pin 300 mil DIP, 24-pin 300 mil SOJ and 22-pin LCC packages providing excellent board level densities.

Output Load * including scope and test fixture. Note: Because of the ultra-high speed of the P4C188/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 Figure 2. Thevenin Equivalent 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).
