P4C1298/P4C1298L ULTRA HIGH SPEED 64K x 4 STATIC CMOS RAM FEATURES Full CMOS, 6T Cell High Speed (Equal Access and Cycle Times) – 15/20/25/35 ns (Commercial/Industrial) – 15/20/25/35/45 ns (Military) Low Power Single 5V±10% Power Supply Output Enable & Chip Enable control functions Data Retention with 2.0V Supply Three-State Outputs TTL/CMOS Compatible Outputs Fully TTL Compatible Inputs Standard Pinout (JEDEC Approved) – 28-Pin 300 mil DIP, SOJ – 28-Pin 350x550 mil LCC DESCRIPTION The P4C1298/L are a 262,144-bit ultra high speed static RAM organized as 64K x 4. 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. Current drain is typically 10 µA from a 2.0V supply. Access times as fast as 15 nanoseconds are available, permitting greatly enhanced system speeds. CMOS is utilized to reduce power consumption. The P4C1298 is available in a 28-pin 300 mil DIP or SOJ, as well as a 28-pin 350x500 mil LCC package, providing excellent board level densities.

Note: Because of the ultra-high speed of the P4C1298, 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).
