The CMOS memories require no clocks or refreshing, and have equal access and cycle times. Inputs are fully TTL-compatible. The RAM operates from a single 5V ± 10% tolerance power supply. CMOS is utilized to reduce power consumption in both active and standby modes. In addition to very high performance, this device features latch-up protection and single-event-upset protection. Access times as fast as 10 nanoseconds are available, permitting greatly enhanced system operating speeds. The P4C147 is available in 18 pin 300 mil DIP packages as well as an 18-pin CERPACK package and LCC.

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. CE is LOW and WE is HIGH for READ cycle. 6. WE is HIGH, and address must be valid prior to or coincident with CE transition LOW. 7. Transition is measured ±200mV from steady state voltage prior to change with specified loading in Figure 1. This parameter is sampled and not 100% tested. 8. Read Cycle Time is measured from the last valid address to the first transitioning address. 15 P4C147 AC CHARACTERISTICS—WRITE CYCLE (VCC = 5V ± 10%, All Temperature Ranges)(2) Sym. -10 -25 -12 -15 -20 -35 Unit Min Max Min Max Min Max Min Max Min Max Min Max Parameter tWC Write Cycle Time 10 12 15 20 25 35 ns tCW Chip Enable Time to End of Write 8 10 12 15 20 25 ns tAW Address Valid to End of Write 8 10 12 15 20 25 ns tAS Address Set-up Time 0 0 0 0 0 0 ns tWP Write Pulse Width 8 10 12 14 15 18 ns tAH 0 0 0 0 0 0 ns tDW Address Hold Time from End of Write Data Valid to End of Write 5 6 7 9 12 15 ns tDH Data Hold Time 0 0 0 0 0 0 ns tWZ Write Enable to Output in High Z tOW Output Active from End of Write 6 5 0 7 0 9 0 0 15 12 0 0 ns ns WE CONTROLLED)(9) TIMING WAVEFORM OF WRITE CYCLE NO. 1 (WE t WC (11) ADDRESS t CW CE t AW t WR t AH t WP WE t AS t DW DATA IN t DH DATA VALID t OW(10, 12) (12) t WZ DATA OUT DATA UNDEFINED HIGH IMPEDANCE CE CONTROLLED)(9) TIMING WAVEFORM OF WRITE CYCLE NO. 2 (CE t WC (11) ADDRESS t AS t CW CE t AH t WR t AW t WP WE t DW DATA IN t DH DATA VALID DATA OUT HIGH IMPEDANCE Notes: 9.

Note: Due to the ultra-high speed of the P4C147, 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 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). 17 P4C147 ORDERING INFORMATION P4C147 xx x x Device Type Speed Package Processing C 0°C to +70°C M –55°C to +125°C MB Mil Temp. with MIL-STD-883 Class B Compliance P Plastic DIP (300 mil) D CERDIP (300 mil) F CERPACK L LCC 10, 12, 15, 20, 25, 35 4K x 1 SRAM The P4C147 is also available per SMD 5962-88587 SELECTION GUIDE The P4C147 is available in the following temperature, speed and package options.
