DESCRIPTION
The P4C168, P4C169 and P4C170 are a family of 16,384-bit ultra high-speed static RAMs organized as 4K x 4. All three devices have common input/output ports.The P4C168 enters the standby mode when the chip enable (CE) control goes HIGH; with CMOS input levels, power consumption is only 83mW in this mode. Both the P4C169 and the P4C170 offer a fast chip select access time that is only 67% of the address access time. In addition, the P4C170 includes an output enable (OE) control to eliminate data bus contention. The RAMs operate from a single 5V ± 10% tolerance power 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 P4C168 and P4C169 are available in 20-pin (P4C170 in 22-pin) 300 mil DIP packages providing excellent board level densities. The P4C168 is also available in 20pin 300 mil SOIC, SOJ, CERPACK, and Flat Pack packages. The P4C169 is also available in a 20-pin 300 mil SOIC package.

* including scope and test fixture. Note: Because of the ultra-high speed of the P4C168, P4C169 AND P4C170 care must be taken when testing these devices; an inadequate setup can cause a normal functioning part to be rejected as faulty. Long highinductance leads that cause supply bounce must be avoided by bringing the VCC and ground planes directly up to the contactor fingers. A high frequency capacitor of 0.01 µF is also required between VCC and ground.
Figure 2. Thevenin Equivalent
To avoid signal reflections, proper termination must be used; for example, a 50Ω test environment should be terminated into a 50Ω load with 1.73V (Thevenin Voltage) at the comparator input, and a 116Ω resistor must be used in series with DOUT to match 166Ω (Thevenin Resistance).
