Four-Bit Parallel Bidirectional Bus Driver ee Distinctive Characteristics © Data bus buffer driver for 8080 type CPU's © Three-state outputs © Low input load current — 0.25mA maximum. © Advanced Schottky processing © High output drive capability for driving system data @ Available in military and commercial temperature bus — 50mA at 0.5V range © Am8216 has non-inverting outputs © Am8226 has inverting outputs @ Output high voltage compatible with direct interface to MOS FUNCTIONAL DESCRIPTION The Am8216 and Am8226 are four-bit, bi-directional bus tional bus. The DO outputs on this side of the driver have a drivers for use in bus oriented applications. The non-inverting special high voltage output drive capability so that direct inter- Am8216, and inverting Am8226 drivers are provided for flexi- face to the 8080 type CPUs is achieved with an adequate bility in system design, amount of noise immunity. Each buffered line of the four bit driver consists of two The GS input is a device enable. When it is “high” the output separate buffers that are three-state to achieve direct bus inter- drivers are all forced to their high-impedance state. When it is face and bi-directional capability. On one side of the driver the a “LOW” the device is enabled and the direction of the data ‘output of one buffer and the input of another are tied together flow is determined by the DIEN input. (08), this side is used to interface to the system side com- Ponents such as memories, 1/O, etc., because its interface is The DIEN input controls the direction of data flow which is TTL compatible and it has high drive (50mA). On the other accomplished by forcing one of the pair of buffers into its high side of the driver the inputs and outputs are separated to _ impedance state and allowing the other to transmit its data. A provide maximum flexibility. Of course, they can be tied simple two gate circuit is used for this function. together so that the driver can be used to buffer a true bi-direc: LOGIC DIAGRAMS Am8216 Am8226 ovo | ovo foo} ma _ woof 14 —oo8, ' t—oos, 00 < 09, 2150 p> 5 0— H 008; - | foo, a Po ORDERING INFORMATION CONNECTION DIAGRAM Top View AmB216 = Am8226 cwesetecr &E]1® 1617 vee Package Temperature Order Order ara ourrur 9652 1s [7 bien SATA wane Type Range Number Number sro ee ote] > 1a f)003 vataoureur Hermetic DIP —85°C to +125°C_ MD8216. = MD 8226 oarainur Op} e gg 13 [1% Bramectionac Hermetic DIP 0°C to +70°C 08216 8226 paraouteur 00)] > Am#22® 421 015 oarainrur Molded DIP -O°C 10 +70°C_— P8216 P8226 oarams oy dy i Dice 0°C to +70°C + AMB216XC__AM8226XC sromncnanar 9 en oarainrur on] vo Poe, SAAB 11-24 .
