Each device features an active low Output Enable control to eliminate data bus contention. The P4C198/L also have an active low Chip Enable (the P4C198A/L have two Chip Enables, both active low) for easy system expansion. The CMOS memories require no clocks or refreshing and have equal access and cycle times. Inputs are fully TTL-compatible. The RAMs operate from a single 5V 10% tolerance power supply. Data integrity is maintained with supply voltages down to 2.0V. Current drain is typically 10 A from a 2.0V supply. Access times as fast as 12 nanoseconds are available, permitting greatly enhanced system operating speeds. CMOS is used to reduce power consumption to a low 715 mW active, 193 mW standby. The P4C198/L and P4C198A/L are available in 24-pin 300 mil DIP and SOJ, and 28-pin 350 x 550 mil LCC packages providing excellent board level densities.

Output Load * including scope and test fixture. Note: Because of the ultra-high speed of the P4C198/L and P4C198A/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 Figure 2. Thevenin Equivalent 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).
