| Part Number | MM74C89 |
| Manufacturer | Fairchild |
| Description | The MM74C89 is a 16-word by 4-bit random access read/ write memory. Inputs to the memory consist of four address lines, four data input lines, a write enable line and a memory enable line. The four bi... |
| Features |
s Wide supply voltage range: s Guaranteed noise margin: s High noise immunity: 3.0V to 15V 1.0V 0.45 VCC (typ.)
s Low power TTL compatibility: fan out of 2 driving 74L s Low power consumption: s 3-STATE output
Note: The timing is different than the DM7489 in that a positive to negative transition of the memory enable must occur for the memory to be selected.
100 nW/package (typ.) s Fast access time: 130 ns (typ.) at VCC = 10V
