MCM21L14

® MOTOROLA MCM2114 MCM21L14 4096-BIT STATIC RANDOM ACCESS MEMORY The MCM2114 is a 4096-bit random access memory fabricated with high density, high reliability N-channel silicon-gate technology. For ease of use, the device operates from a single power supply, is directly compatible with TTL and DTL, and requires no clocks or refreshing because of fully static operation. Data access is particularly simple, since address setup times are not required. The output data has the same polarity as the input data. The MCM2114 is designed for memory applications where simple interfacing is the design objective. The MCM2114 is assembled in 18-pin dual-in-line packages with the industry standard pin-out. A separate chip select (8) lead allows easy selection of an individual package when. the three-state outputs are 0 R-tied. The MCM2114 series has a maximum current of 100 mAo Low power versions (i.e., MCM21 L14 series) are available with a maximum current of only 70 mAo 1024 Words by 4-Bit Organization Industry Standard 18-Pin Configuration Single +5 Volt Supply No Clock or Timing Strobe Required Fully Static: Cycle Time = Access Time Fully TTL/DTL Compatible Common Data Input and Output Three-State Outputs for OR-Ties Low Power Version Available MAXIMUM ACCESS TIME/MINIMUM CYCLE TIME MCM2114-20 MCM21L14-20 MCM2114-25 MCM21 L14-25 200 ns 250 ns MCM2114-30 MCM21 L 14-30 MCM2114-45 MCM21L14-45 15 A9 A4 A5 1 A6 17 A7 16 A8 14 /101 13 1102 Row Select Memory Array 64 ...
