The DP8417 8418 8419 8419X represent a family of 256k DRAM Controller Drivers which are designed to provide No-Waitstate CPU interface to Dynamic RAM arrays of up to 2 Mbytes and larger Each device offers slight functional variations of the DP8419 design which are tailored for differ- ent system requirements All family members are fabricated using Nationals new oxide isolated Advanced Low power Schottky (ALS) process and use design techniques which enable them to significantly out-perform all other LSI or dis- crete alternatives in speed level of integration and power consumption Each device integrates the following critical 256k DRAM controller functions on a single monolithic device ultra pre- cise delay line 9-bit refresh counter fall-through row col- umn and bank select input latches Row Column address muxing logic on-board high capacitive-load RAS CAS and Write Enable Address output drivers and precise control signal timing for all the above There are four device options of the basic DP8419 Control- ler The DP8417 is pin and function compatible with the DP8419 except that its outputs are TRI-STATEThe DP8418 changes one pin and is specifically designed to offer an optimum interface to 32 bit microprocessors The DP8419X is functionally identical to the DP8419 but is avail- able in a 52-pin DIP package which is upward pin compati- ble with Nationals new DP8429D 1 Mbit DRAM Controller Driver Each device is available in plastic DIP Ceramic DIP and Plastic Chip Carrier (PCC) packaging (Continued)
The W03563 is a general purpose variable gain control building block built using an advanced proprietary complementary bi- polar process It is a two-quandrant multiplier so that zero or negative control voltages do not allow signal feedthrough and very high attenuation is possible The W03563 works in current mode rather than voltage mode so that the input impedance is low and the output impedance is high This allows very wide bandwidth for both large and small signals
W03563he W03563 is a dual inverting buffer/line driver with 3-state outputs. W03563he 3-state outputs are controlled by the output enable inputs 1OE and 2OE. A HIGH level at pins nOE causes outputs to assume a high-impedance OFF-state. Schmitt-trigger action at all inputs makes the circuit highly tolerant for slower input rise and fall times.
