N74F399D93TUBE N74F399D93TUBE N74F399D93TUBE Datasheet The other value that must be accounted for is RAS pre- charge, the value that RAS is de-asserted before the next RAS access. This value is 50 ns in 80-ns memory, which was l clock at 16 MHz but is now 2 clocks at 30 MHz. Both of these requirements add two more states to the master control PAL device and thereby ne- cessitate a larger number ofoutputs than was in the pre- N74F399D93TUBE N74F399D93TUBE N74F399D93TUBE Price| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Tj= -400C | | _ | - | | | | | | | _ | _ | | rr | | | | | | | | 1 | >< | | | | | | | | | | | | 25aC | | | | | | 25 0C | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | N74F399D93TUBE N74F399D93TUBE N74F399D93TUBE on stock| Model Number | Density | Total Bytes | Cylinders | Heads | Sectors | | SST58SM/LM008 | 8MB | 8,028,160 | 245 | 2 | 32 | | SST58SM/LM016 | 16 MB | 16,023,552 | 489 | 2 | 32 | | SST58SM/LM024 | 24 MB | 24,051,712 | 367 | 4 | 32 | | SST58SM/LM032 | 32 MB | 32,047,104 | 489 | 4 | 32 | | SST58SM/LM048 | 48 MB | 48,037,888 | 733 | 4 | 32 | | SST58SM/LM064 | 64 MB | 64,028,672 | 977 | 4 | 32 | | SST58SM/LM096 | 96 MB | 96,075,776 | 733 | 8 | 32 | | SST58SM/LM128 | 128 MB | 128,057,344 | 977 | 8 | 32 | | SST58SM/LM192 | 192 MB | 192,151,552 | 733 | 16 | 32 | | | | | | | |
