NEe Microcomputers, Inc. 2048 x 8 BIT STATIC CMOS RAM NEe }LPD447 }LPD447-1 }L PD447-2 ~rn~[~~~~illrnW OESCR IPTI ON The J-lPD447 is a high speed, low power, 2048 word by 8 bit static CMOS RAM fabricated using an advanced silicon gate CMOS technology. A unique circuitry technique makes the J-lPD447 a very low operating power device which requires no clock or refreshing to operate. Since the device has two chip enable inputs, it is suited for battery backup applications. Minimum standby power current is drawn by this device when CE2 equals VCC independently of the other input levels. II Data Retention is guaranteed at a power supply voltage as low as 2V. TheJ-lPD447 is packaged in a standard 24-pin dual-in-line package and is plug-in compatible with 16K EPROMs. FEATU RES Single +5V Supply Fully Static Operation - No Clock or Refreshing required TTL Compatible - All Inputs and Outputs Common Data Input and Output Using Three-State Output Two Chip Enable Inputs...
