The CMOS memory requires no clock or refreshing and has equal access and cycle times. Inputs and outputs are fully TTL-compatible. The RAM operates from a single 5V±10% tolerance power supply. With battery backup, data integrity is maintained for supply voltages down to 2.0V. Access times as fast as 15 nanoseconds are available, permitting greatly enhanced system speeds. CMOS is utilized to reduce power consumption. The P4C1026 is available in a 28-pin 300 mil and 400 mil SOJ packages, as well as Ceramic DIP and LCC packages, providing excellent board level densities.

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. 5. WE is HIGH for READ cycle. 6. CE is LOW and OE is LOW for READ cycle. 7. ADDRESS must be valid prior to, or coincident with CE transition LOW. 8. Transition is measured ± 200 mV from steady state voltage prior to change, with loading as specified in Figure 1. This parameter is sampled and not 100% tested. 9. Read Cycle Time is measured from the last valid address to the first transitioning address.

Note: Because of the ultra-high speed of the P4C1258, 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 µF 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 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).
